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.

Egg & Sperm Quality: The Hidden Key to Fertility Health
Fertility isn’t just about timing it’s about quality. During National Fertility Awareness Week, we’re shining a light on one of the most overlooked aspects of conception: egg and sperm health. Whether you’re actively trying to conceive or planning for the future, understanding how lifestyle, nutrition, and targeted supplementation affect reproductive cells can make a big difference. Why Egg Quality Matters A woman is born with all the eggs she will ever have around one to two million. Over time, that number and quality naturally decline. By the mid-30s, fewer eggs are released, and the likelihood of chromosomal abnormalities increases, which can affect conception and pregnancy outcomes. The good news? Egg quality can be supported with lifestyle changes and fertility-focused supplements. Tips to Support Egg Health Nourish your body: Antioxidants like vitamins C and E, selenium, and CoQ10 protect eggs from oxidative stress. Balance blood sugar: Whole foods, lean proteins, and healthy fats stabilise hormones and support ovulation. Reduce toxins: Limit alcohol, smoking, and environmental toxins like BPA. Prioritise rest & stress management: Chronic stress can impact ovulation and hormonal balance. Supplements like Ovum are designed to provide essential vitamins, minerals, and antioxidants to support egg quality and reproductive health. Femme Health Pre-Conception & Ovulation Support Supplement, formulated to nourish your body for conception. Sperm Health: More Than Just Count Sperm quality isn’t only about quantity it’s about motility (movement), morphology (shape), and DNA integrity. Research shows that sperm health can change within about three months, as that’s how long new sperm take to develop. Ways to Boost Sperm Quality Maintain a healthy weight: Excess body fat can affect testosterone and sperm production. Fuel up: Zinc, folate, vitamin D, and omega-3s support sperm quality. Stay cool: Avoid excessive heat from laptops or saunas on the lap area. Cut back on toxins: Smoking, heavy alcohol use, and recreational drugs can harm sperm DNA. The Power of Preconception Care Preconception health isn’t just for those ready to conceive today it’s a form of body literacy. Understanding your fertility empowers you to make informed choices about your health, family planning, and overall wellbeing. Consider fertility testing or consultations to learn more about: Ovarian reserve testing (AMH, FSH, AFC) Semen analysis Hormone balance panels Nutritional and lifestyle assessments Supplements like Ovum Femme Health Pre-Conception & Ovulation Support can complement these lifestyle and testing strategies, providing targeted nutrients to support both egg and sperm quality. Key Takeaway Both Egg & Sperm Quality are vital to conception, and both can be nourished through lifestyle, diet, and supplementation. Nutrition, stress management, and targeted vitamins play powerful roles in protecting reproductive health. This National Fertility Awareness Week, let’s normalise conversations around fertility because awareness is the first step to empowerment. Because fertility health is whole-body health.
