How to install NeuroNation - Focus and Brain Training v2.20.2 on Android API 9+
Takes about 2 minutes. You'll need roughly 30.2 MB of free storage.
- Grab air.nn.mobile.app.main_2020002.apk — hit the Download button above (30.2 MB). 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 06c7f220bf843341…. Any difference means the file is corrupted or tampered — delete and re-download.
- Open the APK — tap the download notification, or find air.nn.mobile.app.main_2020002.apk in your Files app under Downloads, then tap it. Android's package installer will appear.
- Check the signer — the install screen will name the publisher. For this build it should read CN=Ilya Shabanov, OU=Synaptikon GmbH, O=NeuroNation, L=Berlin, ST=Berlin, C=DE. 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 TRUSTED).
- Done — open NeuroNation - Focus and Brain Training — tap Open on the install screen, or find the NeuroNation - Focus and Brain Training icon in your app drawer (this build targets armeabi-v7a devices).
Common install errors for NeuroNation - Focus and Brain Training
- "App not installed" — usually means an older or differently-signed version is already on your device. Uninstall it first, then retry. Your data may be lost unless you back it up.
