About this app

Tempdrop is a personalized user-specific thermometer that learns how each woman’s minute, daily temperature variations correlate with her specific hormonal fluctuations throughout the ovulatory cycle. It is intended for use with fertility apps or other approaches to fertility monitoring and allows daily, hassle-free, and accurate tracking of your sleeping temperature.

Powered by our patented Active Temperature-Noise Cancellation™ (ATNC) technology, Tempdrop’s accuracy is achieved using multiple sensors and an algorithm developed by top engineers and doctors.
When using sympto-thermal based methods to track fertility and predict ovulation, reliability depends on daily and accurate input of sleeping temperature (also known as BBT).
The accuracy of Tempdrop’s data allows you to identify recurring temperature patterns up to 5 days before ovulation.

Important notice:
Alcohol consumption, medications, and various medical conditions may alter your sleeping temperature. If you have been drinking alcohol a few hours before sleep, make a note on that in your fertility app or notebook and examine the effect on your sleeping temperature. We advise you to track your sleeping temperature with Tempdrop for two full
ovulatory cycles so you can clearly identify the temperature shift and pattern before and after your ovulation day.

Great tool to track cycles!! The basic app is setup great- really easy to use and navigate. Does all the charting you would do by hand. You can even print off charts with your data on them if you wanted to bring to a provider, etc. (haven't tried it yet tho).The sleep info (with subscription) is handy to know especially without any other smart watch, etc. would highly recommend app since it takes work out of charting and can work with wakeups during the night!

I have a love hate relationship with the device. When it works 100% it's great and tells me a lot but I CANNOT get used to the ever changing temps from previous days. If the original temp is accurate why would it change. It has been explained but doesn't make sense still. One it said I ovulated then the next day it changes several temps at once. You should make any life decisions based on it. It can be useful but not as consistent as I need it to be.

Very good experience! It takes a day or two to update temperatures from previous days if the algorithm adjusts. It's easy to chart symptoms. If you are a Marquette Method user, it is best to note your monitor reading in the "notes" section . It won't chart it, but you will have a record. I'm not a premium user. After a few months, previous data on the scroll area disappears, but the graphs are always accessible. It updates with my phone to accommodate a time zone change.
