Install checklist

  1. 1Use an Android 8.0 or newer phone. The optional on-device assistant needs an arm64 phone; its model needs about 5.22 GiB free, and we recommend 8–10 GB free before setup.
  2. 2If the August v0.5.8 preview is installed, uninstall it first. Build 21 is signed by SafeRide’s EAS build service, while the August preview used a separate release key, so Android will not install one over the other. Uninstalling deletes that app’s local drafts. The signing certificate fingerprint is published below.
  3. 3Download the signed APK and compare its SHA-256 value before allowing “Install unknown apps” for your trusted browser or file manager.
  4. 4Open SafeRide, complete onboarding, review permissions, and configure stealth and quick-exit settings before testing.
  5. 5Do not enter real survivor evidence during unsupervised testing; use synthetic reports until safeguarding review approves live pilots.

Pilot caveats

  • This is a public testing preview, not a production, emergency-service, survivor-facing, UNICEF-approved, or Google Play release.
  • Account sign-in, report submission and sync do not work yet because SafeRide’s servers are not online, and new account sign-up is turned off. Reports stay on the phone as encrypted drafts.
  • The optional on-device assistant downloads 4.72 GiB on first use and needs about 5.22 GiB free. Use stable Wi-Fi and keep the device charging.
  • Build 21 has not yet been installed on a physical phone. It has passed automated build and signature checks only; on-device testing, TalkBack and the lower-memory device matrix are pending.

APK trust

Verify before field use.

Treat every APK as sensitive software. This page publishes the exact version, byte size, source commit, and SHA-256 needed to detect a stale or modified download.

What platform does the SafeRide pilot support?

This APK is built for Android 8.0 or newer phones (arm64-v8a, armeabi-v7a, x86, x86_64). The optional on-device assistant needs an arm64 phone. iOS is not included.

Should testers enter real survivor evidence?

No. Use synthetic reports until safeguarding review approves live pilot use.

Why is the model download much larger than the APK?

The signed APK is 146.3 MiB, while the separate on-device LiteRT-LM model is 4.72 GiB. The model is designed to download once, be verified locally, and stay available after restart; that flow was confirmed on the August build and has not yet been retested on build 21.
