## What is Wrist Temperature Tracker?

Wrist Temperature Tracker turns overnight Apple Watch wrist temperature into clear trends, widgets, and cycle context. The app reads existing wrist temperature values from Apple Health; it does not measure body temperature by itself.

Before you start
- You need an Apple Watch that supports wrist temperature sensing.
- Wear it while sleeping. Track Sleep with Apple Watch and Sleep Focus need to be active for at least 4 hours per night.
- After setup or pairing, establishing a baseline usually takes about 5 nights.
- Allow the app to read wrist temperature from Health. If Health has no samples, the app cannot show any values.

Features
- Daily readings plus weekly, monthly, and yearly trends
- Heat maps that show changes from your usual pattern
- Cycle comparisons and temperature context for spotting recurring patterns
- Widgets and complications for quick access to recent data
- Configurable notifications for temperature changes
- A diagnostics area for Health data, notifications, and purchases

Cycle insights help you recognize personal patterns. They are not intended for contraception and do not replace a medical thermometer or diagnosis.

Some features, including advanced comparisons, widgets, and extended views, require an in-app purchase.

### 3/5 — Régression ?

*2026-04-30*

Tous les matin, mon Apple Watch Ultra l’affichait une notification avec ma température. Cette notification a disparue. Problème ? Ou mauvais parametrage (même si je n’ai touché à rien !) ?

Édit 30/04/2026: dans le menu Notification de l’iPhone, je n’ai plus l’appli, donc impossible de vérifier si les notification sont active ou pas

**Developer response:** Merci pour votre message. Ce n’est probablement pas un mauvais réglage de votre part.

Nous avons identifié un problème possible dans la dernière mise à jour : la notification quotidienne pouvait ne plus être déclenchée correctement chez certaines utilisatrices déjà installées. Nous préparons un correctif rapidement.

En attendant, vous pouvez simplement vérifier que les notifications sont toujours autorisées pour l’app, mais si vous n’avez rien changé, le problème vient très probablement de notre côté.

### 4/5 — Temperatur von Apple Watch

*2026-01-20*

Ich finde es toll dass man die von der Apple Watch gemessene Temperatur dort sehen kann und sie sich automatisch einträgt. Leider verstehe ich aber den Rest der App nicht. So viele überlagerte Kurven und komische Zusammenfassungen. 
Eine einfache „Zykluskurve“ (wo man den Beginn evtl. Selbst festlegen kann) wäre schöner.  Für mich so sonst leider zu unverständlich. 

Trotzdem toll dass es die App gibt

### 1/5 — Interpolated

*2025-11-14*

Ist wie Demo und echtes Game, absoluter schrott.

**Developer response:** Danke für dein Feedback. 

Hast du Daten aus deiner Apple Watch?
Kannst du mir dein Problem bitte genau schildern?
Info@bernhardhering.de

### 1/5 — Funktioniert nicht mehr

*2025-11-07*

Hat bis vor 20 Tagen funktioniert....jetzt leider nicht mehr.
Nicht zu empfehlen

**Developer response:** Hi, danke dir für dein Feedback! Schade, dass es aktuell bei dir nicht mehr funktioniert. Magst du mir kurz an info@bernhardhering.de schreiben, was genau nicht klappt? Dann kann ich dir schnell helfen.

### 1/5 — Stopped working

*2025-10-08, version 2.0.0*

Worked well, bought the app, now it hasn’t read my wrist temperature in 5 days now . My watch is recording my temp, it’s the app that’s not reading the watch

### 1/5 — Scam

*2025-07-20, version 2.0.0*

When I went to pay the 1.99 it went through Apple Pay and thankfully it declined because they tried to charge me $54.change.

### 1/5 — Ne fonctionne plus

*2025-06-17*

Depuis deux jours, ne fonctionne plus. À l’ouverture de l’application il faut entrer le mot de passe du compte Apple pour restaurer l’achat. Cela ne fonctionne pas.

**Developer response:** Désolé pour le blocage. Un bug empêchait la restauration d’achat et demandait sans cesse le mot de passe. La version 2.4.1 corrige ce point. Mettez l’app à jour, ouvrez-la, puis
    appuyez sur « Restaurer l’achat » dans les réglages. Si cela ne marche toujours pas, contactez-moi via https://bernhardhering.de et j’examinerai votre compte immédiatement.

### 3/5 — Das was ich gesucht habe

*2025-06-16*

Da mir die exakte Temperaturangabe bei Health zu tief im Menü vergraben ist, habe ich eine App wie diese gesucht. Und eigentlich wäre sie absolut perfekt, wenn sie auch die zweite Nachkommastelle mit angeben würde.  Leider wird mir aber nur die erste angezeigt, wodurch die App fürs Zyklustracking unbrauchbar wird.

### 2/5 — Requires me to restart watch ~ every 3 days

*2025-05-24*

This app is not reliable.  It stops working every 2 to 3 days.  Only way to get it to work again is to restart my watch.

### 1/5 — What???

*2025-03-25, version 2.0.0*

This doesn’t work?? I have got I watch ultra and I have my watch on me 24/7!! And no wrist temp?? A month I had this app?? Rubbish don’t bother
