Setting up your Tempdrop

Pull the armband through the frame to form a loop
Click your sensor into the armband frame
Place the Tempdrop on your arm and adjust your size. The sensor will sit over the soft dip just below the armpit hairline. Tip of the sensor points toward the elbow. 
Thread the hook through a lace loop to lock your size- slide it on and off each day


  • Your armband must be very firm (without causing discomfort) to maintain adequate skin contact overnight with minimal movement. If the sensor moves, it can lead to poor quality data.
  • The sensor may be loose in the frame, be sure to hold onto it when it's off your arm

Using your Tempdrop

Turn on the sensor. Press and hold the pink button for 2-3 seconds. Slow flashing green indicates it is now on. 

Place the Tempdrop on your arm and adjust the position.

Go to sleep- leaving it on all night even if you get up to the bathroom or to care for baby.
When you are up for the day, remove your Tempdrop. The sensor will auto shut off after it has been removed and it cools below 86F/30C


  • Keep it on all night even if your sleep is interrupted
  • The sensor will auto shut off after it has been removed and it cools below 86F/30C

Important information

Before using this product, please read the following 

Tempdrop is a wearable sleeping temperature thermometer for use along with a Symptothermal Method Fertility Awareness (STM) to track your Menstrual cycle.

Following the directions will help prevent incorrect use of the product.

The Tempdrop sensor algorithm can, in some cases take up to 60 days to best learn your personal temperature patterns. We encourage users to keep in mind that it may take up to the full 2 months to see the best resultsIf you are already tracking your basal body temperature (BBT), you can continue to do so for a time to validate that Tempdrop’s readings correlate with your regular thermometer cycle chart. It’s normal for Tempdrop results to be slightly higher or lower than oral readings.

Alcohol consumption, medications, and various medical conditions may alter your sleeping temperature.

If you have any concerns about your results in the first 60 days, please Contact Us for troubleshooting help.
