What's New in Blood Oxygen SpO₂ Tracker

2.5.8

October 26, 2026

Fixed an issue that could count a blood oxygen measurement more than once after reopening the app. Late-synced and deleted Health measurements are now reflected in the app. The Apple Watch “Today” count now uses the current calendar day.

Schneller Service

Alles funktioniert wie beschrieben

Response from developer

Danke für deine tolle Rückmeldung!

Trash App

Not sure why Apple allows this in their App Store. Does not work as advertised on the iPhone or Apple Watch.

Response from developer

Hi, Did you Allow HealthKit Access to the app?

Refund

Please refund not syncing with my Apple Watch

Response from developer

I’m sorry syncing didn’t work for you. I can’t issue or confirm a refund through a review. If you still need help with the original purchase or the sync issue, please email me at mail@bernhardhering.de; keep purchase details out of the public review.

Funktioniert leider nicht

Auf meiner Apple Watch Ultra 2 wird die App zwar gestartet, doch es erscheint nur ein schwarzer Bildschirm. In der Health-App wird angezeigt, dass die Blutsauerstoffapp nicht verfügbar ist.

Response from developer

Hi, Danke für das Feedback. Kannst du einmal vorher die iOS App starten bitte? Und dann die Watch App. Die Berechtigungen für HealthKit sind manchmal nicht deterministisch.

Enganação

Um lixo de aplicativo

Response from developer

Sinto muito que a experiência tenha sido tão decepcionante. Se você ainda precisar de ajuda, escreva para mail@bernhardhering.de explicando em qual tela o app falha e qual versão usa. Prefiro entender o problema a lhe dar uma resposta genérica.
