About this app

NativeProbe is an open-source React Native playground for exploring, testing, and understanding real device capabilities. It's not a generic "device info" app or a benchmark tool — every probe lets you do something: trigger a sensor, request a permission, watch a value change live, and see the Expo API behind it.

13 interactive probes across device info, live sensors, and system APIs:
• Device, Display, Battery, Network
• Accelerometer, Gyroscope, Magnetometer
• Permissions, Location, Haptics, Biometrics, Deep Links
• A local Capability Report you can copy or share

No account, no backend, no cloud sync, no telemetry. Your device data stays on your device.

Built for developers, QA engineers, and anyone learning React Native / Expo — every probe screen names the Expo API it's built on.
