Not worth the price

The app itself is ok I suppose, although lately when contacting support the emails do not send. 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.

Long term user moving away from this device due to recent reliability issues / poor customer service

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.

Great device, bad app

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.

App dysfunction

I would like to use the app, but it take a long time to open and crashes within a few seconds.

Déçue

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.

FAQ

What does the Tempdrop app do?

The Tempdrop app works with the Tempdrop thermometer to record minute temperature variations throughout the night. This data helps users pinpoint their basal body temperature, understand hormonal fluctuations, and track or predict their menstrual cycle phases, including ovulation.

How does the Tempdrop app help with fertility tracking?

By accurately measuring basal body temperature overnight, the app identifies subtle shifts that correlate with hormonal changes during the menstrual cycle. This allows users to pinpoint ovulation and gain insights into their fertile window, supporting fertility awareness methods.

Is the Tempdrop app free to use?

The app is free to download and use, but it is designed to complement the Tempdrop thermometer device. In-app purchases may be available for additional features or services related to the device and its data analysis.

What are the limitations of the Tempdrop app?

The app and its sensor are intended to enhance fertility monitoring and cycle tracking, not as a substitute for contraception or birth control. It is not a medical device and should not replace professional medical advice. The app's predictions are not suitable for irregular cycles and depend on correct, consistent use.

Who is the target audience for the Tempdrop app?

The app is designed for individuals who want to actively track their menstrual cycle, identify ovulation, and gain a deeper understanding of their fertility. It is particularly useful for those interested in fertility awareness methods and seeking to monitor their reproductive health.
