Tempdrop is the first of its kind - a personalized user specific thermometer that learns minute temperature variations, correlated with hormonal fluctuations throughout the ovulatory cycle (e.g. Estrogen, Progesterone), thus identifying recurring temperature patterns up to 5 days before ovulation.
This app is communicating with your Tempdrop sensor via Bluetooth 4.0 and sends the data for analysis on our cloud algorithm server. Your characteristic sleeping temperature will be displayed shortly after.

TempDrop is amazing!!

This device has changed my life! I use the Symptothermal Method of Birth Control. As a nursing mother it’s very hard to get accurate temps with an oral BBT. TempDrop is a lifesaver! It is worlds easier for me to turn it on, put it on, go to sleep and wake up and sync and adjust my chart accordingly than it is for me to remember to temp after a broken night of sleep. The makers of the TempDrop are fabulous and work really hard to make sure their product works well and I appreciate that very much. Maybe one day we will be able to automatically sync to our charts but until then I am happy to be able to chart the way I do and feel peace of mind in what is going on with my body!

Thanks, TempDrop. I’d be lost without you!

Great product in progress!

Yes, the app has some bugs that keep cropping up, but this is a brand new kind of hardware, and there are bound to be some software issues that go along with it. Michael Vardi, the inventor of TempDrop, is always available for users, and is personally invested in making sure things are working as well as possible. This is a company to watch!

Great start

I love that I get to be a part of this company from the start. That being said, there are adjustments and occasional bug fixes. I can’t wait until there is more integration with other charting apps. And I would really love a battery indicator in the app.
