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.

Very good product in progress

I’d really like to see compatibility between Kindara and Tempdrop, and is like to be alerted to battery issues before I start experiencing them, but overall a job very well done. I’m looking forward to the future updates. Excellent product, and I do recommend it to anyone who wants to track fertility using their temperature as a sign.

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!

Needs more functionality

The device works pretty well overall. It’s not very comfortable to wear since the armband is basically a bra strap it feels uncomfortable on your skin and I can’t sleep in a bra comfortably. I’ve tried a lot of methods from the Facebook support group but haven’t found a comfortable alternative.
The app works okay I took one star away for it not being compatible with any apple apps in automatically adding information to tracking apps or Apple health.
I took another star away because the app itself does not display a temperature chart or have menstrual cycle tracking which is a very very basic function.
