User Reviews

User reviews repeatedly flag the app as inaccurate or nonfunctional for measuring blood oxygen, criticize the subscription/trial model as misleading or overpriced, and note that it offers little value beyond what Apple Health provides. Several reviews mention difficulty using the app and lack of clear guidance or essential features. Overall, main concerns center on accuracy, payment model, and absence of meaningful capabilities.

Pros

No clear positive benefits consistently mentioned in user reviews.

Cons

Inaccurate or unreadable oxygen data: the app does not measure or is unreliable for blood oxygen saturation.
Subscription model concerns: free trial issues and inability to cancel, with perceived misleading pricing.
Lack of essential functionality: fails to provide current oxygen readings, is redundant with Apple Health, and offers limited standalone value.
Confusing user experience: unclear how to measure blood oxygen and absence of a dedicated test button.
