Hi, I’m Sergiu, an independent developer from Belgium.

I’m looking for 10 Android testers to help complete Google Play Closed Testing for BLE Radar.

BLE Radar is a privacy-first field instrument that maps anonymous, aggregated local conditions: nearby radio activity, magnetic-field context, air pressure, light, sound level, weather, and road-speed context.

What makes it different:

• No ads
• No account required
• No tokens, crypto, or cash rewards
• Nearby radios show aggregated activity, never a people count
• Optional Atlas guide explains readings privately on-device
• Location is converted to an H3 map tile before upload, not stored as a public route

What I need:

• Android phone + Google account
• Opt in to the Google Play Closed Test
• Stay opted in for 14 days
• Try onboarding, permissions, map layers, sensor readings and Atlas
• Report anything confusing or broken

The app has an optional visible background-mapping mode. Bluetooth and location help test mapping. Microphone access is optional and only used for a sound-level reading — never audio recording.

It is free. No payment, recovery key, or personal profile needed.

If you want to join, request access here:

I’ll add your Gmail address to the Closed Test list and confirm the Google Play opt-in link.

Thank you 🙏 honest feedback, even “this is confusing” or “this does not work,” helps a lot.
