Box contents

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
Thread the hook through a lace loop to lock your size


  • 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.
  • You can wear your Tempdrop sensor in a high sports bra as an alternative position

Using your Tempdrop


Before wearing your Tempdrop, turn on the sensor by long-pressing the button until it starts to slow flash green


Wear your sensor in your chosen position and go to sleep


When you are up for the day, remove your Tempdrop


  • 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.

If you are using an STM to prevent pregnancy naturally, we recommend not relying on your Tempdrop results for at least 60 days or until you are confident your results are following your cycle pattern.

If you are already tracking your basal body temperature (BBT), continue to do so for the first 60 days to validate that Tempdrop’s readings correlate with your regular BBT 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.
