Why a direct APK instead of the Play Store
Direct APK install
- Works because opinion-trading apps are restricted from the Play Store
- You control exactly which version you install
- Requires enabling “install unknown apps” once
Play Store install
- Not available for this category of app
- Would normally auto-update in the background
- Standard route for most other apps, just not this one
What permissions this APK asks for
Camera
Used only during identity/KYC verification to scan documents — not accessed in the background.
Storage
Used to cache market data and images locally so the app loads faster on repeat visits.
Notifications
Used to alert you when a market you’re watching is about to close or resolve.
Network access
Required for live market prices, placing predictions, and wallet transactions.
How to confirm your download is genuine
3 quick checks before you install
- Open the downloaded file’s properties and confirm the size is close to
21 MB— a file that’s much smaller or larger has likely been altered. - After installing, go to Settings → Apps → Probo → App details, and confirm the package name reads
com.probo.probo. - Let Google Play Protect finish scanning the file on install — it should complete without a warning for the official build.

Common questions about the APK
What exactly is an APK file?
It’s the installer format Android uses to package an app — the same type of file the Play Store installs behind the scenes, just downloaded and installed manually here.
Why does Probo need camera and storage permissions?
Camera is used only for document verification during KYC; storage is used to cache data for faster loading. Neither is accessed silently in the background.
How do I know this APK hasn’t been tampered with?
Check the package name, file size, and version match the specification table above, and confirm Play Protect doesn’t flag it on install.
Does installing an APK harm my phone or void warranty?
No — it only requires enabling a standard Android setting for installs outside the Play Store.
