Sub4Sub Pro runs in your browser — no install needed
Open the site on any phone or desktop browser, sign up, and you can earn coins and run campaigns straight away. Nothing to download, nothing taking up storage. If you would still rather have an app icon on your Android home screen, the optional APK below is the same platform in an app wrapper.
Website (recommended)
Android, iPhone or desktop. Nothing to install, always the current version.
Android APK (optional)
Same account, same coins, same campaigns — packaged as a home-screen app.
Installing the APK
The APK is served directly from this site rather than through the Play Store, so Android asks for permission the first time:
- Tap the download button above and let the file finish downloading.
- Open it. Android will ask whether to allow installs from this source.
- Allow it, then confirm the install.
That "unknown source" prompt appears for every APK installed outside the Play Store — it is Android describing where the file came from, not a verdict on the file. If you would rather not see it at all, use the website; it is the same product.
Frequently asked questions
Do I need the app to use Sub4Sub Pro?
No. Everything works in a browser on phone or desktop — signing up, linking a channel, earning coins, and running campaigns. The app is a convenience, not a requirement, and nothing is locked behind it.
Is the APK on the Google Play Store?
Not currently. It is a direct download from sub4subpro.com, so Android will warn about installing from an unknown source the first time — that warning appears for any APK installed outside the Play Store and is not specific to this one. If you would rather not install anything, use the website instead; it does the same things.
What's different in the app?
Functionally nothing. It wraps the same site in an app shell, so it is the same account, the same coins, and the same campaigns whichever one you open. You can switch between them freely.
Is there an iPhone or iOS app?
No. iPhone users get everything through the website in Safari or any mobile browser, which works the same way the Android app does.
