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.

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.

Tempdrop is unique because it's a wearable fertility monitor that gives you freedom and options to suit your specific needs.

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!

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.

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. 

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. 

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!

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.

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.
