How to install Hardest IQ Test v1.1.8 on Android API 16+
Takes about 2 minutes. You'll need roughly 4.9 MB of free storage.
- Grab websoftstarinfosystemsllp.iq_test_9.apk — hit the Download button above (4.9 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 7938b884aa4bf0b7…. Any difference means the file is corrupted or tampered — delete and re-download.
- Open the APK — tap the download notification, or find websoftstarinfosystemsllp.iq_test_9.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=IQ Test, O=Websoftstar. 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).
- Done — open Hardest IQ Test — tap Open on the install screen, or find the Hardest IQ Test icon in your app drawer.
