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.

I absolutely love this app. It’s so easy to use the armband and has helped me understand my body even better. I’m also obsessed with its ability to track your sleep pattern. I will gladly pay the $5 a month after my free trial ends for the premium subscription.

The reasons I’ve given this 4 stars instead of 5 is because there is no place on the app where you can write notes. There’s a few things that happen during my cycle that are not available in the symptoms portion, and some of the common symptoms women experience (acne, nausea, etc) are not even an option. If they could fix these things in the app (especially a notes section) I would give this 10 stars if I could!

5/5 for the TD device, 4/5 for the app

After recently getting married, I decided to come off the HBC that I had been on for the last 15 years to prepare my body to get pregnant. I was diagnosed with PCOS early on in my youth and didn’t know what to expect from my body. My sister, who had been a FAM user for years, bought me a TempDrop as a wedding gift and after the first night of using it, I was hooked.

I’ve only ever had one issue with the device which was a glitch, I think. Tech support was right there waiting to assist but the glitch corrected itself and I had no further issues and didn’t need tech support. The device itself takes a little getting used to as you do sleep with it on your arm but I never had an issue sleeping comfortably with it.

The app itself I give 4/5 stars. I love the aesthetic of other apps and the TempDrop app just isn’t there, yet. The TempDrop team is working hard to take user advice and make changes and I’m excited for the new updates rolling out soon. I would like to see more options (custom data, CM, cervix position, etc) but navigation and selections are pretty good so far. I have faith that they’re hearing the user community and will continue to roll out new features the users have on their wishlists.

Inaccurate cycle information

I contacted support about this issue a week ago but haven’t heard anything back. I bought the Tempdrop device because I thought it would help me more accurately determine my cycle days and help me with the natural family planning method. My cycles are extremely regular and so solely using the calendar method has been effective for me. But I felt it would be more responsible to also track my temperature to decrease the probability of getting pregnant even more. However, this app isn’t useful for this because it has listed me as being in the follicular phase over my entire cycle! The app even said at one point that I was estimated to be 4 days from my period, which was accurate, but it still listed me as in the follicular phase. This is impossible and doesn’t help me track my cycle at all, which was the whole reason I spent $169 on the device and upgraded to the premium app. I am disappointed and will likely return the device soon.
