How to install GPA Calculator v1.3.3 on Android API 16+
Takes about 2 minutes. You'll need roughly 3.3 MB of free storage.
- Grab com.husseinelfeky.gpacalculator_13.apk — hit the Download button above (3.3 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 82c04324c6d40f7c…. Any difference means the file is corrupted or tampered — delete and re-download.
- Open the APK — tap the download notification, or find com.husseinelfeky.gpacalculator_13.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=Hussein El Feky, OU=Mobile Development, O=Hussein El Feky, L=Cairo, C=EG. 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 GPA Calculator — tap Open on the install screen, or find the GPA Calculator icon in your app drawer.
