Private strategy room for hard calls. Android beta build v76.

Download Android APK
Install: Android APK first. The app is about 55 MB.
Model: The default local model setup is about 584 MB and downloads inside CAST after first launch.
Already downloaded the approved model? Use Android's file picker under Advanced import and choose gemma3-1b-it-int4.litertlm. Wider beta builds reject other model files until Cast publishes hashes and device gates.
  1. Download the APK on Android.
  2. Open it and allow install from this browser if Android asks.
  3. Create or continue local-only.
  4. Install the local model from CAST's Model setup screen. Use Wi-Fi. Android shows a download notification and CAST verifies the model after it finishes.

CAST runs local-first when the model is installed. Account verification, feedback upload, model download, and app updates require internet.
