Install in 3 Steps — Android and iOS
Android install takes about two minutes from start to first login. iOS users can add the app directly from the App Store link on this page without any settings change. For Android, because the APK comes from our site rather than Google Play, you need to allow one setting before it installs — the steps below walk you through it clearly. After
that first install, updates happen automatically inside the app. Your account data carries over; you never need to re-register.
- Step 1 — Download the APK — Tap the Android download button on this page. Your browser will save the iron33 APK file (around 30MB) to your phone's download folder.
- Step 2 — Allow Install from Unknown Sources — Open your Android Settings, go to Apps or Security, find the browser you used to download, and enable 'Install unknown apps' for it. This is a one-time step.
- Step 3 — Open and Sign In — Tap the downloaded file to install, then open the iron33 app. Sign in with your existing account credentials or set up biometric login when prompted.
- iOS — App Store Direct — iOS users tap the App Store link on this page. No settings change needed. Sign in after install and your account syncs automatically.
