Contact RobertWhat does Strata add to Apple Health?
Strata shows your existing records as data layers and exports them to CSV, JSON or Markdown. You can then use them in spreadsheets, your own scripts or local AI tools.
Do I need an Apple Watch?
What matters is the data already in Apple Health and the read access you grant. An Apple Watch can contribute data, as can your iPhone and other Health-connected apps. An empty category has nothing to export.
Do my health data leave my device?
Strata processes and exports on-device. The app does not automatically upload your health data to a server. If you choose to share an export or upload it to another tool, that tool’s terms apply.
Does the app include AI analysis?
Strata provides structured data. Analysis happens in a tool you choose, such as an AI model running locally. Strata does not provide diagnoses, treatment recommendations or medical interpretations.
Which devices and languages are supported?
Strata is available for iPhone with iOS 17 or later and iPad with iPadOS 17 or later. The interface supports German and English. Available data depend on your device, Health records and read permissions.
Is it really a one-time purchase?
Yes. Strata is a one-time purchase with no subscription. The US App Store currently lists $9.99. Your purchase is charged at the price displayed in your local App Store.
Why is it called Strata?
Strata means layers. The app organises your health records into six data layers, from activity to mental wellbeing.
