Install the koin28 App in 3 Steps
Getting the app onto your phone takes about two minutes. Android users download the APK file directly from koin28 — no third-party store needed. iOS users follow the standard App Store flow. Before you open the file on Android, go to Settings, find your browser or file manager under 'Install unknown apps', and toggle it on. That one setting is all that
stands between you and the full lobby. Once installed, sign in with your existing account credentials or complete a new registration inside the app itself. Your account balance, transaction history, and saved payment methods — including any linked DANA or OVO account — carry over automatically.
- Download the APK or App — Visit koin28 on your phone and tap the download button for Android APK, or search for koin28 in the App Store for iOS.
- Allow Install from Unknown Sources — On Android, open Settings and enable 'Install unknown apps' for your browser or file manager. This is a one-time step.
- Open and Sign In — Tap the installed app, enter your account details, and authenticate with fingerprint if your device supports it. The full lobby is ready immediately.
