Putting it on the phone

  1. Tap Download the app above, then open the file when it finishes.
  2. Android blocks apps that do not come from the Play Store until you allow it. You allow it on a settings screen called Install unknown apps, for the place the file came from (the browser you downloaded it with). Then open the file again.

Faster readings (optional)

Android lets an app take 4 Wi-Fi readings every 2 minutes. To remove that limit on this phone:
  1. Find Build number. On a Samsung Galaxy (S8 and later): Settings > About phone > Software information > Build number. On a Google Pixel: Settings > About phone > Build number.
  2. Tap Build number seven times, until the phone says You are now a developer!
  3. Go back one screen. Developer options is now at the bottom.
  4. In Developer options, under Networking, turn off Wi-Fi scan throttling (Android 10 and newer).
  5. In the app, tick I turned off the reading limit on this phone.

First build. It has been tested with made-up readings only and has not yet run on a real phone. Treat the first walk as a test.
