Tester group for Sensor Phone — an Android app that turns a spare phone into a guard: it reacts to sound, motion or vibration and sends a notification to your current phone. For your car, your bike, the cellar, the front door, or as a pet camera.

Google requires 12 testers over 14 days before an app can be published. That's what this group is for: join, and you get access to the closed test on Google Play.

How to join:
1. Join this group
2. Opt in: https://play.google.com/apps/testing/com.schwarzdev.sensorphone
3. Install it: https://play.google.com/store/apps/details?id=com.schwarzdev.sensorphone

Use the same Google account for all three steps, or the install won't work. Please keep the app installed for the full 14 days — that's the part Google counts.

Pro features are unlocked for all testers within 12 hours of signing up in the app — no purchase needed. Just create an account and they'll appear on their own.

With two Android devices you can try everything — one old phone watches, your current phone receives the alerts. With a single device you'll only see the monitor side; it still counts for the test, but you won't see much.

Any feedback is welcome, even short notes on what was confusing or didn't work.
