v1.0

Sideloadable release build. Signed with the standard Android debug key so it installs directly; native code is compiled -O3.

asset size for
echo-1.0-arm64.apk 24.5 MB phones — this is the one you want
echo-1.0-universal.apk 28.8 MB also carries x86_64, for emulator testing

Verified on a Pixel 9, Android 17 (API 37): 42 JVM unit tests and 11 instrumented tests passing; the Base model sustains 5.29× realtime on 4 threads, putting a 10-minute chunk at ~113 s.

Install

adb install -r echo-1.0-arm64.apk

On Windows, scripts\verify-on-device.ps1 also grants RECORD_AUDIO/POST_NOTIFICATIONS and exempts the app from battery optimisation.

First run: grant mic + notifications, then Settings → Speech model → download Base (57 MB), then tap record.

Audio and transcripts never leave the device. Note that the app records people who have not consented — see the privacy section in the README before using it around others. Hindi/Marathi transcription is not yet verified end to end; see docs/VERIFICATION.md.
