Device requirements
To complete camera-based activities in Coherence, use a phone or tablet with a front-facing camera and a supported operating system:
| Platform | Requirement |
|---|---|
| iPhone and iPad | iOS or iPadOS 17 or later |
| Android | Android 9 (API 28) or later. See the supported devices. |
| Camera | A front-facing camera |
Reliable measurements also depend on camera performance. The device should keep about 25 frames per second or higher during a capture, and 30 fps is recommended. A supported operating system alone doesn’t ensure reliable capture.
Before you begin
Choose a well-lit space, keep your face clearly visible, and follow the on-screen guidance. For breathing measurements, rest the device on a stable surface with your face and chest in view. For more tips, see Getting a good measurement.
