The Tempdrop app is designed to complement the Tempdrop device - a personalized user-specific thermometer that captures minute temperature variations throughout the night to pinpoint the basal body temperature. Detected variations in temperature correlate with hormonal fluctuations throughout the menstrual cycle. When used with the Tempdrop device, this app can help users to pinpoint ovulation and effectively track and predict the varying phases of the cycle.

You have to physically send an email from your email account if you want it to actually reach them. I do not recommend tempdrop. I bought the original device and recently it has been draining the battery so quickly that it needs a new battery within a few days. I let tempdrop support know and they acknowledged the malfunction on their end (and not something I had done). What was the response? Sorry your device is outside the warranty here’s a discount to buy a new one. No thank you! I’ll be trying something else. ### 1/5 — Long term user moving away from this device due to recent reliability issues / poor customer service *2026-08-16, version 3.28* I’ve used Tempdrop for about 8 years and have purchased three devices in that time. When my previous device developed problems, support’s solution was essentially to buy another one, which I did. Now, only about a month into using my newest Tempdrop, the app crashed while syncing and then wouldn’t open at all. Support instructed me to delete and reinstall the app. After doing so, the Home screen began displaying my most recent temperature when I selected ANY previous date, even though the correct historical temperatures still appear in the Chart tab. When I reported this discrepancy—with screenshots—support responded by explaining how to access my temperature history, rather than addressing the fact that I was reporting changed/incorrect app behavior. Throughout this exchange, their responses have felt dismissive and condescending, repeatedly explaining basic functionality instead of addressing the actual problems I’ve described. Tempdrop is marketed to people who rely on continuous temperature data. Having hardware or software fail in the middle of a cycle isn’t a minor inconvenience—you cannot go back and collect a missed temperature later. This is now the second cycle in which either Tempdrop’s hardware or software has caused problems for me. After 8 years, three devices, recurring reliability issues, and this customer-service experience, I’ve lost confidence in Tempdrop. I’m researching alternatives and may simply return to a basic BBT thermometer. For such an expensive product, I expected considerably better reliability and support. ### 3/5 — Great device, bad app *2026-08-03, version 3.28* I love my Tempdrop device for reliably getting accurate temps. But this app is awful. Tons of content all over the home page. The articles look like ads. After the recent update my totally normal cycle was labeled “irregular” from day 1. Huh? Please simplify the user interface. I just want my temps! I have to use a different app for actually tracking my chart. ### 1/5 — App dysfunction *2026-08-03, version 3.28* I would like to use the app, but it take a long time to open and crashes within a few seconds. ### 3/5 — Déçue *2026-07-26* La dernière maj fonctionne très mal. L’application se ferme seule au bout de quelques secondes, dans l’indication de la glaire on a deux fois « humide ». De plus, je suis déçue de voir qu’il faut payer pour avoir certaines fonctionnalités alors que le Tempdrop est quand même assez coûteux… Le suivi de la température est intéressant et permet de mieux comprendre le cycle. ### 3/5 — Good, but recent app crashes make it impossible to use *2026-07-25, version 3.28* I haven’t had a problem with temp drop for the past few years. It’s been an amazing tool for tracking my temperature overnight and it has always synced flawlessly. However, since the most recent update, I now haven’t been able to sync my Tempdrop for the past 3 days in a row because the app is immediately crashing. These temperatures are vital for me, and I feel as though I’ve been “flying blind” for the past few days because the actual wearable Tempdrop doesn’t have a visible temperature display as a backup to know what my lowest temp is overnight in the event that it doesn’t sync with the app. And now with the app crashes, it’s been impossible to know those readings. I’ve always been happy with the app and service, but this has left me extremely frustrated the past few days. Developers, please address this so the app no longer immediately crashes! ### 4/5 — Edit: so far, so good *2026-07-25, version 3.28* Overall the app is fairly good. I am in my third month, and I’m curious to see how long it takes of consistent tracking before the predictions are accurate. I definitely like knowing when my period is actually going to arrive! I also appreciate the sleep tracking, but I wish it was a little more able to tell when I am asleep/awake. Still, a nice bonus! ### 1/5 — So useful but way too expensive, fragile and poor customer service *2026-07-23* True investment on this device, I was very happy with it. After only a couple of months of normal use, the device broke without me doing anything special except sleeping on it (what else would you want to use it for?)… the customer service told me that because of physical damage, the warranty wasn’t working, and that they couldn’t find any solution. It is such a scam seeing the price of the device. Not worth any other « more simple » thermometer with free tracking apps! ### 3/5 — New homepage is just ads and articles *2026-07-20, version 3.28* I’ve had a subscription for a few years but this newest update is the pits. When I open the app I want to see the data I pay yearly for, not ads and articles. The articles look interesting if I needed the info, but it’s just kinda rude to take away the scrolling format of MY DATA and replace with the apps content. Please change it back. ### 1/5 — Recent app update has made it borderline unusable *2026-07-20, version 3.28* App used to work great and the thermometer cuff itself is great. but since a recent update it is incredibly glitchy and cumbersome to work with. I’ve started just recording my temps in a different app for cycle tracking because despite the extra work it’s still less annoying than using this app ## Frequently asked questions about Tempdrop ### What does the Tempdrop app do?
