Android first, iOS later. The APK isn’t ready to download yet — the install steps below are for when it ships.

Direct APK
In progress

The Android APK is a build in progress (Android 8.0+). When it ships you’ll sideload it — your device will ask you to allow installs from unknown sources, which is normal for a direct download.

How to install

Android install steps for when the APK is ready. iOS comes later. No account until you unlock.

Android — APK sideload

Build in progress · Android 8.0+ · No Play Store needed

  1. When the APK is ready — tap the download on this page. Chrome may warn “unknown file type” — tap Download anyway.
  2. Open the file from your notification or Downloads. If prompted, tap Allow from this source (or enable Install unknown apps for your browser).
  3. Tap Install → Open. calibrEAT opens on the welcome screen — tap Enter your license code when you’re ready to unlock.
  4. Lost the prompt? — open Files → Downloads → calibrEAT.apk and tap again.
Safety note: “Unknown sources” just means outside the Play Store. The APK is signed by us — Android lets you review permissions before you tap Install. You can turn the permission off after.
