FAQs
What is Tempdrop?
What is Tempdrop?
Tempdrop is a smart wearable thermometer and charting app combo that brings an all-in-one fertility monitor to your smartphone.
The Tempdrop sensor is worn on the upper arm during sleep to accurately derive a core nightly sleeping body temperature for the purposes of ovulation tracking. Tempdrop is uniquely able to arrive at an accurate body temperature thanks to a combination of advanced sensors and sophisticated algorithms. Combine temperatures with other fertility symptom tracking within the app to pinpoint ovulation each cycle. Our charting app has a free version option or you can choose to upgrade to our premium features to take advantage of automatic cycle interpretation and fertility insights. As a bonus, our premium option allows you to track your sleep data as well.
If you’re, trying to conceive, charting to know your body, or practicing fertility awareness long-term, the Tempdrop fertility monitor is designed to take the stress out of ovulation tracking. For those that are postpartum, have irregular cycles, work shifts, are a light sleeper, or love to sleep-in, Tempdrop delivers accurate cycle tracking data that is tailored to you.
How does Tempdrop work?
How does Tempdrop work?
Tempdrop is a smart wearable thermometer and charting app for fertility tracking.
The Tempdrop sensor is worn under your upper arm using the Tempdrop armband during sleep. Each night, it collects thousands of data points on your body temperature and sleep motion. We derive your single nightly sleeping temperature from the data using advanced algorithms.
After removing the device, initiate a sync using the Tempdrop sensor and fertility app ( Apple Store, Google Play) and Tempdrop will sync your sleeping temperature using Bluetooth Low-Energy (BLE) to your smartphone. You can track additional fertility symptoms in the charting feature for a complete solution.
The Tempdrop wearable fertility tracker will replace the traditional method of BBT temping so you can stop losing sleep and take the stress out of cycle charting. Click here to learn more.

How is Tempdrop different from other basal thermometers?
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 temping whilst I am using other birth control methods?
Can I start temping whilst I am using other birth control methods?
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 dependant 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.
Does it matter what time I wake up or how long I sleep?
Does it matter what time I wake up or how long I sleep?
We are happy to inform you that your days of alarm-clock wake-ups to take your temperature are over. With the Tempdrop wearable fertility monitor, your temperature is monitored continuously throughout the night. This means that whenever you wake up, your sleeping temperature will be waiting to sync to your futility app.
The same applies if you experience disturbed sleep or a shift worker. You will still be able to retrieve a result to chart your cycles. Here are the headlines...
- Tempdrop must be turned on and worn for a minimum of three hours
- Two hours of sleep must be detected for a valid result. Sleep time does not have to be consecutive
As best practice, turn on and wear you Tempdrop fertility tracker just before going to sleep and remove it as soon as you are up for the day. If your sleep is disturbed for a period of time during the night, leave the sensor on.
Is Tempdrop safe?
Is Tempdrop safe?
Perfectly safe!
The Tempdrop fertiloty monitor only transmits a Bluetooth signal in the first 30 seconds when being turned on and when you remove the device from your body and manually initiate syncing. It uses Bluetooth 4.0 to transmit data, which is a very low energy signal (approximately 1000x less than a cell phone). Syncing is less than 30 seconds per day.
The Tempdrop fertility tracker is powered by a standard coin cell type watch battery while it is being worn and recording. No wireless signal or connections are transmitted during sleep.
Finally, The Tempdrop wearable fertility tracker is made from medical grade materials and has FCC and CE certifications. The metal sensor is medical grade stainless steel which can contain trace amounts of Nickle.

I'm trying to get pregnant. How can Tempdrop help me?
On average, properly timed sexual intercourse can triple the likelihood conceiving naturally. By tracking your ovulation, you can identify the days with the highest probabilities of success. The Tempdrop wearable fertility monitor allows you to do just that by allowing you to consistently track accurate body temperature and other fertility symptoms in a stress-free way.
I have irregular cycles - Will Tempdrop work for me?
I have irregular cycles - Will Tempdrop work for me?
Yes! Tempdrop is designed to support all cycle types, including irregular ones.
Tracking fertility can be challenging for those with irregular cycles, but Tempdrop offers a flexible solution that adapts to your unique patterns.
The Tempdrop sensor continuously tracks your basal body temperature (BBT) while you sleep, providing real-time data to help identify ovulation. This is especially helpful for those with irregular cycles, as it takes the stress out of collecting your daily temperature results when cycles are long.
If your cycles are considered irregular, the Tempdrop app won’t estimate your next ovulation, but it still tracks and interprets* your temperature data to confirm when ovulation has taken place. Once ovulation has passed, the app can estimate your next period due date, providing valuable insights for cycle tracking, timing pregnancy tests, or understanding your body's natural rhythms. If pregnancy occurs, the confirmed ovulation date can also be used to calculate an estimated due date with greater accuracy.
Users with irregular cycles are also encouraged to track and log Cervical Mucus observations, as this fertility marker can be used to identify when an ovulation attempt is near. When Cervical Mucus is logged, the app can give additional fertility window insights.
Tracking Fertility with Irregular Cycles
While future ovulation estimates can’t be given when cycles are irregular, Tempdrop can help by:
* Monitoring your temperature patterns over time to recognise ovulatory trends.
* Combining other fertility signs, like cervical mucus tracking, to identify when fertility is high.
* Predict when the next period is due after ovulation is confirmed.
* Identifying the right time to test for pregnancy.
* Assist in accurately predicting a due date based on ovulation timing.
Final Thoughts
Having irregular cycles doesn’t mean you can’t use Tempdrop - it simply means that instead of relying on predictions, you’ll focus more on real-time data interpretation. The Tempdrop fertility monitor remains a powerful tool to help you understand your cycle and fertility health, even when patterns aren’t predictable.

FROM TEMPDROP TO TINY TOES: HOW KATIE UNLOCKED HER FERTILITY MYSTERY
“Katie, your cycles look fine, nothing to worry about.”
That’s what she kept hearing. And on paper, it made sense. Her cycles were mostly regular. Ovulation usually happened at a normal time. GP tests didn’t show anything unusual.
But Katie knew something was off. She’d started to notice the occasional late ovulation and a few irregular cycles creeping in. Plus, tracking her basal body temperature with an oral thermometer was stressful, her shift work made it nearly impossible to take a reading at the same time every morning and get accurate feedback.
When she came to see me, I suggested trying Tempdrop. It would take the pressure off her routine while still giving us accurate, consistent data to work with. Katie ordered one straight away and started tracking.
Within just one month, the mystery started to unravel. We discovered she had a short luteal phase, something that was invisible on standard GP checks and easy to miss when you only look at cycle length.
With that knowledge, she was able to get the medication she needed. Fast forward, and Katie is now holding her beautiful baby girl, all because she became her own fertility detective and we worked together to uncover what was really going on.
Sometimes, the answers aren’t in the “average” cycle data. They’re in the details you uncover when you track consistently, and with the right tools.

Learn moreWhy 3 Months Really Matters to fertility by Ilana Garsin
How Long Does It Take to Improve Hormone Health and Fertility? When it comes to hormone health and fertility, one of the first questions I’m often asked is: “How long will it take before I see results?” The honest answer? It takes time, because your body works in beautiful, natural cycles. Why 3 months really matters The eggs you ovulate today actually began developing about three months ago. It takes roughly 90–100 days for an egg to mature before it’s ready for ovulation. So the lifestyle choices, stress levels, supplements, and acupuncture sessions you have now are influencing the egg you’ll release in three months’ time. You’re born with all the eggs you’ll ever have — you can’t create new ones — but what you can change is the environment those eggs develop in. Through acupuncture, nutrition, and reducing stress, you can improve blood flow, oxygenation, and hormonal balance, creating the best possible conditions for your eggs to mature and ovulate. You can also influence the uterine environment — ensuring your endometrial lining is thick, healthy, and receptive, ready to support implantation and early pregnancy. That’s why I recommend allowing at least 3–4 menstrual cycles when addressing hormonal or fertility issues. This gives your body time to rebalance, your hormones to regulate, and your reproductive system to respond. Acupuncture works with your body’s rhythm Acupuncture supports the body through these cycles, helping to: Improve blood flow to the ovaries and uterus Support healthy ovulation and implantation Balance hormones like oestrogen, progesterone, and FSH Reduce stress and calm the nervous system Improve sleep, digestion, and energy — all vital for fertility However, acupuncture isn’t a “quick fix.” Just as it takes three months to nurture an egg, it takes several cycles for acupuncture to create lasting changes in your hormonal patterns and reproductive health. Over these weeks, acupuncture gently retrains your body to function in a more balanced way — regulating cycles, improving flow, reducing PMS, and supporting better-quality eggs. Conditions acupuncture can help with Acupuncture can support a wide range of hormonal and fertility-related conditions, including: Irregular or absent periods (amenorrhoea) Painful or heavy periods (dysmenorrhoea, menorrhagia) Polycystic Ovary Syndrome (PCOS) and Polycystic Ovaries (PCO) Endometriosis High FSH or low AMH Unexplained infertility Thin or poor-quality endometrial lining Luteal phase defect or short cycles Recurrent miscarriage Thyroid-related fertility issues Perimenopause and menopause symptoms such as hot flushes, anxiety, insomnia, and mood swings Whether the issue lies with ovulation, egg quality, hormone imbalance, or stress, acupuncture works to restore communication between the body’s key systems — helping you feel more balanced, calm, and in tune with your natural cycle. The stress–hormone connection One of the most powerful (and often overlooked) influences on fertility is stress. When we’re under constant stress, our brain shifts into “survival mode.” The hypothalamus and pituitary gland, which act as your body’s hormonal control centres, reduce communication with the ovaries — known as the hypothalamus–pituitary–ovarian (HPO) axis. This can delay or even suppress ovulation, affect hormone levels, and disrupt your cycle. Acupuncture helps calm the stress response, balance cortisol, and restore that vital communication between brain and ovaries — allowing your body to return to a more regular rhythm. Many women notice more consistent cycles, improved mood, and better sleep once stress levels begin to settle. Don’t forget about sperm health Coincidentally, sperm also follows a similar timeframe. Although sperm are made fresh every day, it takes around three months for sperm to fully mature. That means the steps your partner takes now — through acupuncture, supplements, nutrition, and lifestyle — will influence the quality of his sperm three months down the line. Supporting both partners together often leads to much better fertility outcomes. Track your progress with BBT During this time, tracking your Basal Body Temperature (BBT) can be a wonderful tool. By noting your temperature daily, you can start to see clear signs of ovulation, hormone shifts, and improvements in your cycle health. Many of my patients find it empowering to actually see the changes happening as their charts become more balanced. See Product Supplements and self-care for three months These same three months are also the perfect window to support your body with good-quality supplements, nourishing foods, and restorative rest. Think of it as a 90-day investment in your future fertility and hormone health. Every acupuncture session, every supplement, and every good night’s sleep adds up to the changes you’ll see in a few months’ time. Find the perfect fertility supplement for you Menopause and hormonal balance take time too The same principle applies to perimenopause and menopause. Hormonal shifts during this stage don’t happen overnight — and neither does balance. Acupuncture helps ease symptoms like hot flushes, night sweats, anxiety, poor sleep, and mood changes, but it works best when given time to regulate your body’s feedback systems. With consistency, patience, and care, most women notice gradual, sustainable improvements rather than quick, short-lived fixes. Patience brings results Whether you’re trying to conceive, regulate your periods, or manage menopause symptoms, patience and consistency are key. Just as you wouldn’t expect to feel fit after one visit to the gym, your hormonal system also needs time to respond and reset. By committing to 3–4 cycles of acupuncture, tracking your cycle, supporting yourself with the right supplements, and giving your body space to heal, you’re laying the foundations for lasting hormonal balance and fertility health. Your body is always working for you — sometimes, it just needs the time and support to show it.
