Description
Fertility and ovulation tracking that finally fits your life.
Traditional basal body temperature tracking works - but it comes with rules. Wake up at exactly the same time every day, take your temperature before you move, speak or even think about getting out of bed. Every single day. Miss a day and your data is compromised. It’s accurate, but it’s exhausting.
Tempdrop removes all of that.
Why does BBT tracking matter?
Your basal body temperature shifts subtly throughout your cycle, rising after ovulation and dropping before your period. Tracked consistently, these tiny changes reveal your fertile window, confirm ovulation, and give you a real, data-backed picture of your hormonal health - something no app that just counts days can do.
BBT tracking is one of the most effective natural methods for understanding your cycle, whether you’re trying to conceive, avoiding pregnancy naturally or simply want to know your body better.
A smarter way to track...
Tempdrop is a small, comfortable wearable you put on before bed and forget about. While you sleep, it continuously monitors your temperature - then syncs everything to your app by morning.
No alarms. No rigid routines. No data lost before life got in the way.
Built on proven scientific methods, Tempdrop delivers the accuracy of traditional BBT tracking - without any of the restrictions. Its smart algorithm learns your unique patterns over time, filtering out sleep disturbances and adapting to irregular schedules, so your readings stay accurate even when your sleep isn’t perfect.

How it works
Tempdrop takes the most effective method of fertility tracking and makes it effortless. Here’s how:
Step 1 - Wear it to bed. Slip the Tempdrop sensor into the armband and wear it on your upper arm before you go to sleep. That’s it. No setup, no alarms, nothing to remember in the morning.
Step 2 - It tracks while you sleep. Throughout the night, Tempdrop collects thousands of temperature and movement data points from your body. Its smart algorithm filters out any disturbances - restless nights, late wake-ups, shift work - to calculate one accurate, reliable basal body temperature reading.
Step 3 - Sync in the morning. When you wake up, remove the sensor and open the Tempdrop app. A quick Bluetooth sync sends your overnight data straight to your smartphone - available on iOS and Android.
Step 4 - Understand your cycle. Your temperature is automatically added to your chart, building a clearer picture of your cycle over time. Log additional symptoms, track your fertile window and get personalised insights - all in one place.
The result? Accurate BBT tracking without the 6am alarms, rigid routines, or missed readings. Just consistent, meaningful data that helps you understand your body better every single day.

FAQs
Does it matter what time I wake up or how long I sleep?
Not at all - this is one of the things that makes Tempdrop different. Traditional BBT tracking requires you to wake up at exactly the same time every day, but Tempdrop's algorithm accounts for variations in your sleep duration and wake time. Whether you had a restless night, a lie-in, or an early start, your data remains accurate and reliable.
The only requirement is that the sensor is worn for a minimum of 3 hours, with at least 2 hours of sleep detected during that time - and those 2 hours don't need to be consecutive. So even if your sleep is broken or interrupted, Tempdrop can still give you a valid reading.
I have irregular cycles, can Tempdrop be my period tracker too?
Absolutely - Tempdrop is designed to support all cycles, including irregular ones.
Tracking fertility with an irregular cycle can feel overwhelming, but Tempdrop takes the stress out of it by continuously monitoring your basal body temperature while you sleep and adapting to your unique patterns over time.
While the app won't estimate future ovulation dates for irregular cycles, it still tracks and interprets your temperature data to confirm when ovulation has taken place.
You can also log cervical mucus observations in the app alongside your temperature data - a really useful addition for irregular cycles, as it can indicate when an ovulation attempt is near and give you additional fertile window insights.
So while your cycle might be unpredictable, Tempdrop helps you understand what's happening in your body every step of the way.
I am trying to conceive, how can Tempdrop track my fertile days?
Timing is everything when it comes to conception - and properly timed intercourse can triple your likelihood of conceiving naturally. That's where Tempdrop comes in.
By consistently tracking your basal body temperature overnight, Tempdrop helps you identify your fertile window and pinpoint the days with the highest chance of success. No guesswork, no counting days - just accurate, personalised data from your own body.
And because Tempdrop removes all the stress from daily temperature tracking, you can focus on what actually matters - without your fertility journey taking over your life.
Is Tempdrop safe?
Completely - Tempdrop is designed with your safety in mind from the ground up.
The sensor only transmits a Bluetooth signal twice: in the first 30 seconds when turned on, and when you manually initiate syncing after waking up. Syncing takes less than 30 seconds, and no wireless signal is transmitted at all while you're sleeping. The Bluetooth 4.0 signal it uses is extremely low energy - approximately 1,000 times less than a standard mobile phone call.
While wearing it overnight, Tempdrop runs purely on a standard coin cell watch battery with no wireless connections active.
It's made from medical grade materials, including a stainless steel sensor, and holds CE certification. Please note the stainless steel may contain trace amounts of nickel, so if you have a known nickel sensitivity it's worth bearing that in mind.
Will I have to pay an ongoing subscription?
Tempdrop is unique because it's a wearable fertility monitor that gives you freedom and options to suit your specific needs.
The Tempdrop fertility app has both free and premium versions, so you can choose the level of support that works best for you.
Every Tempdrop user gets their first 2 months of Premium completely free, giving you full access to Tempdrop's advanced fertility insights, automatic interpretation and additional tracking features from the start.

How is Tempdrop different from other basal thermometers?
As opposed to taking a manual waking temp, Tempdrop offers continuous monitoring, filtering out waking times to give you a true nightly sleeping temperature. The smart algorithm learns your unique nightly and monthly patterns to filter variables that can otherwise skew temp results. Worn high up in the inside of the upper arm, the wearable fertility monitor captures an axillary reading making it more accurate than surface skin temperature.
The accompanying charting fertility app encourages tracking multiple fertility signs to better guide you in understanding your cycle and fertile window. If you already have a favourite fertility app, you can freely use it with your Tempdrop data. The choice is yours!
Can I start using Tempdrop whilst on birth control?
Yes. You can start using the Tempdrop ovulation tracker device straight away, even if you are using another form of birth control, such as hormonal birth control.
Tempdrop is not dependent on your cycle status. However, the sooner you start wearing Tempdrop, the sooner it can get through the 'learning phase' (Tempdrop learns your sleep and environmental patterns). This will enable you to catch your first ovulation post hormonal birth control (HBC) or postpartum (PP), whatever your personal circumstances are.
Which smartphones can I use with Tempdrop?
Tempdrop is compatible with a wide range of smartphones. Simply visit your app store and search for the Tempdrop app. If you can download it, you're good to go!

If you're 30-something, your Instagram feed probably looks a bit like ours here at femme HQ: full of life milestones - engagements, weddings, baby announcements. But lately, we've noticed something else creeping in alongside them: egg health and egg freezing content, popping up more and more. It's got us talking about why this is suddenly the topic everyone's discussing.
Welcome to Know Your Eggs.
Egg health and egg freezing are having a moment. From TikTok explainers to friends comparing AMH results over brunch, it's suddenly everywhere but a lot of the noise raises more questions than it answers.
So we made Know Your Eggs: a guide that cuts through it, bringing together fertility science, nutrition and specialist expertise in one place. This blog covers the essentials:

Egg Health 101: What You Actually Need to Know
When people talk about egg health, they're usually talking about two different things: egg count and egg quality - so what's the difference between the two?
Egg count (also called ovarian reserve) refers to how many eggs you have remaining. Women are born with all the eggs they'll ever have — typically 1–2 million at birth, dropping to around 300,000 by puberty. That number naturally declines over time, with a sharper drop after the age of 35. Of that original supply, only around 300–500 eggs will ever actually be ovulated across a reproductive lifetime.
Egg quality refers to how genetically "normal" an egg is, which affects its ability to fertilise and develop into a healthy pregnancy. Quality tends to decline with age too, but unlike count, it can be influenced by lifestyle and environmental factors.
You can have a high egg count but lower egg quality, or vice versa - which is exactly why looking at just one number rarely tells the full story.
Our bodies do such a great job of selecting high-quality eggs.
— Maisie Hill, Period Power.
Rather than framing this decline as a loss, Hill reframes it as proof of an incredibly selective process - your body working hard behind the scenes to put forward only the best-quality eggs for ovulation.
What is ovarian reserve?
Ovarian reserve is essentially your body's remaining "supply" of eggs. It's not something you can top up, but understanding where you stand can help you make more informed decisions about fertility planning, timing, and whether options like egg freezing might be worth exploring.
AMH Testing, Explained Simply
AMH (Anti-Müllerian Hormone) is a hormone produced by small follicles in the ovaries. A simple blood test can measure your AMH level, giving a general indication of your ovarian reserve - roughly how many eggs you likely have left.
The key thing to remember: AMH reflects quantity, not quality.
It's a useful clue, not a fertility score. A high AMH doesn't guarantee healthy eggs, and a lower AMH doesn't mean pregnancy isn't possible. It's one piece of the puzzle, best interpreted alongside other factors and, ideally, with guidance from a clinician.
A few numbers worth knowing:
You're born with roughly 1–2 million eggs, down to around 300,000 by puberty
Only around 300–500 eggs will ever be ovulated in a lifetime
Male factors contribute to roughly 40–50% of fertility challenges in couples — this isn't a one-sided story
How to Improve Egg Quality: Start With What's on Your Plate
Egg quality can be influenced by diet, supplementation and lifestyle. None of it needs to be perfect to make a difference. A Mediterranean-style diet, rich in antioxidants and healthy fats, is consistently linked with better assisted-reproduction outcomes and it's a common thread across the fertility research, from clinical studies to books like It Starts with the Egg.
Even with a varied diet, stress, digestion and food quality can affect nutrient intake which is where targeted supplementation can help fill specific gaps.
We love Ovum because their approach is backed by real science, 550+ clinical studies in fact, with formulas designed to support egg and reproductive health across that key 90-day window.

Your Temperature Tells a Story
Egg health isn't only about nutrition - understanding your cycle is part of the picture too. After ovulation, progesterone causes a small rise in basal body temperature (BBT) that stays raised until your next period, which is why overnight tracking (rather than a bedside thermometer) can help pinpoint ovulation and luteal phase length.

Egg Freezing, On Your Terms
Life doesn't follow one script and family-building doesn't have to either.
In England and Wales, the average age of someone having their first baby rose from 23 in 1970 to 29 in 2020 (ONS). And the numbers show it: according to the Human Fertilisation and Embryology Authority (HFEA), the UK's fertility regulator, egg freezing cycles nearly tripled between 2019 and 2023 — from 2,567 to 6,932 a year. The average age at freezing in 2023 was 35, with women returning to thaw and use their eggs at an average age of 40.
As life timelines have become more varied, more women are exploring egg freezing, not as a last resort, but as an informed option.
Less "last resort." More informed option — if you want it.
Sources: HFEA, Egg Freezing: A Factsheet (hfea.gov.uk); Office for National Statistics.
Elective vs Medical Egg Freezing
Egg freezing involves collecting and storing unfertilised eggs for possible future use, giving people more flexibility around family-building or medical treatment.
Elective egg freezing (more time + flexibility)
Not ready to start a family
Waiting for the right partner
Career or personal timing
Solo parenthood planning
Gender-identity considerations
Medical egg freezing (preserving options before care)
Chemotherapy or radiotherapy
Surgery that may affect fertility
Conditions such as endometriosis
Some hormone therapies
Gender-affirming care pathways
A future pregnancy is never guaranteed and outcomes can by influenced by your age at freezing, the number of mature eggs stored, sperm factors and future treatment. But the HFEA is clear that age at freezing (not age at use) is the single biggest factor in future success, which is why more people are choosing to explore it earlier.
The Process, in Brief
Egg freezing moves through three broad phases: an initial fertility assessment and specialist consultation (including AMH testing and a scan), a treatment cycle involving around 10–14 days of hormonal stimulation followed by a short egg-collection procedure, and finally rapid freezing (vitrification). In the UK eggs can be frozen for up to 55 years with consent renewed every 10.
The full Know Your Eggs guide breaks this down step by step, including what to expect at each stage and how to prepare your body and mind for treatment.
Egg Freezing: Quick Answers
How many eggs should I freeze?
There's no single magic number some clinics discuss ranges such as 15–20 mature eggs for a good chance of success, but it depends on age, ovarian reserve and individual goals.
Curious about stimulation timelines, storage, and vitrification? The full Know Your Eggs guide answers the questions people ask most.
Progress Over Perfection, Always
Fertility is having a moment on social media right now - "fertility maxxing," endless supplement stacks, and no shortage of things you're apparently supposed to be doing. It's a lot.
This guide is full of genuinely useful lifestyle tips - nutrition, sleep, supplements, tracking, and more - but none of it is meant to become another source of pressure. Stress itself can work against the very hormones and processes we've talked about here, so piling on guilt over an imperfect diet or a skipped supplement isn't doing you any favours.
Think of this less as a checklist to nail perfectly, and more as a menu: pick what feels doable, make small changes where you can, and let go of the rest.

If you’re comparing Tempdrop vs Oura Ring for cycle tracking, fertility awareness, or ovulation confirmation, you’re not alone.
Wearable technology has made temperature tracking more accessible than ever. But not all wearables are designed for the same purpose. While both Tempdrop and Oura Ring collect temperature-related data, the way they measure it, interpret it, and apply it to fertility tracking is fundamentally different.
This article focuses only on what matters for menstrual cycle tracking:
Basal body temperature (BBT)
Ovulation confirmation
Fertile window identification
Temperature accuracy and consistency
If your goal is understanding your cycle and fertile window - rather than general wellness metrics - those differences matter.
Why Basal Body Temperature Matters for Cycle Tracking
Basal body temperature is your body’s resting temperature, measured during sleep or immediately upon waking. Across a menstrual cycle, BBT follows a predictable pattern:
Lower temperatures before ovulation
A sustained temperature rise after ovulation
Higher temperatures during the luteal phase
This post-ovulation temperature rise is one of the most reliable physiological markers that ovulation has already occurred.
That distinction is important. Basal body temperature does not predict ovulation in advance - it confirms that ovulation has happened. For many people using fertility awareness methods, this confirmation is essential for:
Identifying fertile and non-fertile days
Understanding cycle length and regularity
Supporting pregnancy planning or avoidance
Accurate ovulation confirmation depends on clean, consistent temperature data.
How Tempdrop Measures Basal Body Temperature
Tempdrop is designed specifically for fertility awareness and cycle tracking.
It is worn on the upper arm overnight and measures axillary temperature, which is closely linked to core body temperature. Importantly, Tempdrop does not rely on a single temperature reading. Instead, it:
Collects temperature continuously throughout sleep
Uses an algorithm to filter out disturbances such as movement, changes in sleep position, or environmental variation
Produces a stable basal body temperature value for each night
This approach removes many of the challenges associated with traditional oral BBT tracking, such as waking at the same time every day or disrupted sleep.
Crucially, this technology is aligned with how basal body temperature is used in fertility awareness - as a retrospective marker of ovulation, identified through sustained temperature shifts.
Scientific Validation of Axillary Temperature for Ovulation Tracking
A peer-reviewed study published in Sensors (MDPI, 2025) evaluated the use of an axillary temperature wearable for cycle tracking and ovulation timing across 194 menstrual cycles.
The study found that:
Axillary temperature data could accurately identify the post-ovulation temperature rise
The fertile window and ovulation timing could be determined using overnight temperature measurements
The resulting temperature curves clearly reflected menstrual cycle phases
This research supports the use of axillary temperature wearables for reliable ovulation confirmation based on basal body temperature patterns.
While the study did not compare specific consumer brands, it validates the underlying measurement approach that Tempdrop uses.
How Oura Ring Tracks Temperature
The Oura Ring is a multi-purpose wellness wearable designed primarily for:
Sleep tracking
Readiness and recovery metrics
General health insights
As part of this broader functionality, Oura tracks skin temperature variation at the finger. According to Oura and independent reviews, this data is presented as:
Night-to-night temperature deviations
Trends relative to an individual baseline
Importantly, Oura does not present its temperature data as basal body temperature. Instead, it focuses on changes in skin temperature over time, which may be influenced by:
Environment
Circulation
Illness
Stress
Sleep conditions
In reviews such as Who What Wear’s Oura Ring review, temperature tracking is framed as a general wellness indicator rather than a fertility-specific tool.
Skin Temperature vs Basal Body Temperature: Why the Difference Matters
This distinction is key when comparing Tempdrop vs Oura Ring for fertility use.
Basal body temperature tracking requires:
Consistency
Reduced noise
Alignment with physiological ovulation markers
Skin temperature trends, while useful for overall health awareness, are not the same as basal body temperature and are not designed specifically for ovulation confirmation.
Tempdrop’s approach is purpose-built for identifying:
Sustained post-ovulation temperature shifts
Clear cycle patterns
Fertility-relevant insights based on BBT methodology
Oura’s approach is broader, offering temperature data as one input among many for wellness trends, rather than a dedicated fertility signal.
When Oura Ring Is the Right Choice: General Health & Wellness
It’s important to say this clearly: Oura Ring is not the wrong technology - it’s the right technology for a different goal.
If your primary focus is general health and wellness, rather than fertility awareness or ovulation confirmation, Oura Ring may be the better fit.
Oura Ring is designed to support:
Sleep quality and recovery insights
Daily readiness and wellness trends
Long-term changes in health metrics
Broad lifestyle awareness rather than cycle-specific interpretation
As part of this wider wellness picture, Oura tracks skin temperature variation, presenting it as a trend relative to your personal baseline. This can be useful for noticing:
Changes related to illness or recovery
Stress or lifestyle impacts
Overall physiological patterns over time
For users who want a single wearable to support general wellbeing, rather than focused fertility tracking, Oura Ring’s multi-metric approach makes sense.
However, this broader focus is also its limitation when it comes to menstrual cycle tracking.
Choosing the Right Tool for the Right Goal
When comparing Tempdrop vs Oura Ring, the most important question isn’t which device is better overall - it’s what are you using it for?
If your goal is general wellness, sleep trends, and lifestyle insights, Oura Ring is designed for that purpose.
If your goal is basal body temperature tracking, ovulation confirmation, and cycle understanding, Tempdrop is built specifically for that role.
Tempdrop’s technology aligns directly with fertility awareness methods and is supported by peer-reviewed research validating axillary temperature tracking for identifying ovulation timing and fertile windows.
Oura Ring’s technology aligns with a broader wellness framework, where temperature is one signal among many rather than a fertility-specific metric.
Tempdrop vs Oura Ring for Ovulation Confirmation
When comparing the two specifically for ovulation confirmation:
Tempdrop
Designed exclusively for fertility awareness
Measures axillary temperature overnight
Filters disturbances to produce a true basal temperature curve
Aligns with fertility awareness methods and BBT interpretation
Supported by peer-reviewed research validating this measurement approach
Oura Ring
Designed for general wellness and sleep tracking
Measures skin temperature at the finger
Presents temperature as a trend or deviation
Not designed specifically to confirm ovulation via BBT patterns
For users whose primary goal is understanding their menstrual cycle, this difference in design philosophy is critical.

Final Thoughts: Choosing the Right Technology for Your Cycle
When choosing between Tempdrop and Oura Ring, clarity comes from matching the technology to your intention.
Oura Ring is well suited to people seeking a comprehensive wellness wearable that tracks sleep, recovery, and long-term health trends - with temperature variation as part of that picture.
Tempdrop, by contrast, is designed specifically for people who want to understand their menstrual cycle through basal body temperature, confirm when ovulation has occurred, and gain fertility-focused insights based on established physiological patterns.
If your priority is general health, Oura Ring may be the right choice.
If your priority is cycle tracking and ovulation confirmation, Tempdrop offers technology built for that exact purpose.
Learn how to track your basal body temperature (BBT) to understand ovulation, monitor fertility patterns, and gain insights into your menstrual cycle. This guide covers tools, charting tips, and how combining BBT with methods like the Symptothermal Method can improve accuracy and support reproductive health.
Fertility and ovulation tracking that finally fits your life.
Traditional basal body temperature tracking works - but it comes with rules. Wake up at exactly the same time every day, take your temperature before you move, speak or even think about getting out of bed. Every single day. Miss a day and your data is compromised. It’s accurate, but it’s exhausting.
Tempdrop removes all of that.
Why does BBT tracking matter?
Your basal body temperature shifts subtly throughout your cycle, rising after ovulation and dropping before your period. Tracked consistently, these tiny changes reveal your fertile window, confirm ovulation, and give you a real, data-backed picture of your hormonal health - something no app that just counts days can do.
BBT tracking is one of the most effective natural methods for understanding your cycle, whether you’re trying to conceive, avoiding pregnancy naturally or simply want to know your body better.
A smarter way to track...
Tempdrop is a small, comfortable wearable you put on before bed and forget about. While you sleep, it continuously monitors your temperature - then syncs everything to your app by morning.
No alarms. No rigid routines. No data lost before life got in the way.
Built on proven scientific methods, Tempdrop delivers the accuracy of traditional BBT tracking - without any of the restrictions. Its smart algorithm learns your unique patterns over time, filtering out sleep disturbances and adapting to irregular schedules, so your readings stay accurate even when your sleep isn’t perfect.
