How to Install
Since this app is downloaded directly (not from the Play Store), Android will ask for one extra permission the first time. It's completely normal — just follow these steps.
- Tap "Download the App" above. The file (VantelumCBT.apk) will save to your phone's Downloads folder.
- Open the downloaded file. Your phone may show a warning like "For your security, your phone is not allowed to install unknown apps from this source." This is normal Android behaviour for any app installed outside the Play Store.
- Tap "Settings" on that warning, then enable "Allow from this source." Go back and open the file again — it will now install normally.
- Open the app and start practicing. Try 5 free questions per subject, then unlock full access with Paystack or a WhatsApp PIN whenever you're ready.
