- Grab com.example.usbserial.chordtuner_4.apk — hit the Download button above (62.8 KB). If your browser warns about APK files, choose Keep or Download anyway — that warning fires on every APK, not just this one.
- Trust your browser to install — on Android 8+ go to Settings → Apps → Special access → Install unknown apps, pick the app you downloaded with (Chrome, Firefox, Files, etc.), and flip Allow from this source. On older Android, toggle Unknown sources under Security.
- (Optional) Verify the file — compute the MD5 of the downloaded APK and make sure it matches a05ffca8689b8160…. Any difference means the file is corrupted or tampered — delete and re-download.

- Check the signer — the install screen will name the publisher. For this build it should read CN=Andrey Skachkov, OU=Unknown, O=Far Quest, L=Krasnodar, ST=Unknown, C=RU. If it doesn't match, cancel — you have the wrong file.
- Review permissions & tap Install — scroll the permission list, then confirm. If Play Protect flags it, tap Install anyway (this APK was scanned as UNKNOWN).
