Great app for cycle tracking

Love the app. There is premium features at an additional cost but you can get lots of data in the free version, and you can also manually interpret your own data which is great for fertility awareness.
Love the most recent update.

Bon produit

Le produit est de qualité, la cohérence entre mon suivi sur une autre application que j’ai depuis 2023 qui ne fait pas la température basale et Temdrop est au rendez-vous donc le calcul de la température basale est clair et cohérent avec mon cycle.
Cependant, aujourd’hui pour le même prix d’autres applications proposent le même service avec un vrai suivi de cycle. Donc je dirais qu’aujourdhui Temdrop est trop cher.

Le service client (en anglais) est très réactif ! J’avais un problème de pile ils m’ont offert 4 mois d’abonnement gratuit.

4/5 étoiles car le produit répond à ses promesses.

Response from developer

Thank you for your thoughtful feedback! We’re so glad to hear that Tempdrop’s temperature tracking has been accurate and consistent with your cycle, and that our support team was able to help quickly when you had a battery issue. We also really appreciate your feedback about pricing and cycle-tracking features. We’re always working to improve the Tempdrop experience, and feedback like yours helps us understand what matters most to our users. 💛

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.

Pas fiable

Sur le principe l’idée est bonne. Pour les observations du type glaire cervicale ce serait bien de pouvoir écrire une note car les possibilités de description ne sont pas très complètes. L’application a régulièrement de gros beugs. Actuellement, impossible de l’ouvrir… Or le suivi de la fertilité en symptothermie notamment nécessite d’être régulier et d’avoir des données chaque jour. De plus le capteur est très couteux (plusieurs centaines d’euros) et met plusieurs semaines avant de se calibrer correctement, donc ne plus pouvoir entrer de données c’est aussi devoir recommencer à zéro…
C’est grave que ce ne soit pas fiable à ce point.

Response from developer

Merci d’avoir pris le temps de partager votre expérience. Nous sommes désolés que les bugs de l’application aient autant perturbé votre suivi, surtout lorsque la régularité et la continuité des données sont essentielles en symptothermie. Nous comprenons également votre remarque concernant les observations de glaire cervicale : pouvoir ajouter une note libre serait effectivement utile lorsque les options proposées ne correspondent pas exactement à ce que vous souhaitez noter. Nous transmettons ce retour à notre équipe produit. Concernant l’impossibilité actuelle d’ouvrir l’application, nous souhaitons vraiment vous aider à résoudre ce problème. N’hésitez pas à contacter notre équipe Support@temp-drop.com afin qu’elle puisse examiner votre situation et travailler avec vous pour trouver une solution. Nous savons que le capteur représente un investissement important et que perdre l’accès à vos données ou ne plus pouvoir les saisir est particulièrement frustrant. Nous voulons faire mieux et nous espérons avoir l’occasion de regagner votre confiance.

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.
