🐗 BOAR offline APKs
Android APKs of BOAR, an open-source research assistant that answers on the phone, with sources. The offline APKs carry the models and the library inside the APK, so BOAR never needs the network, not even on first launch. Files too big for a GitHub release (2 GiB per file) live here.
🚀 Latest: v2.0.0-rc2
Release notes: BOAR v2.0.0-rc2 on GitHub Signed with BOAR's key (
7cf514f9…): installs over BOAR 1.x, rc1 and the normal rc2 APK, keeping your models and chats.

On first launch BOAR copies these out of the APK, joins the model's pieces (under 1 GiB each), checks every file against its SHA-256, then works in airplane mode. First launch needs a few GB of free space for that. Other models and packs can be added later from the app, which needs internet.
Tested: the rc2 offline APKs use rc1's packaging plus the split model pieces; their airplane-mode test on a phone is still to come. rc1's was done (see the history below).

🛠️ Build it yourself
Branch feat/offline-bundle, from the repository root:
BOAR_OFFLINE_MODEL=qwen3-4b-instruct-2507-q4km BOAR_VERSION_NAME=2.0.0-rc2 scripts/build-offline-apk.sh release
The script takes the model files from your machine and checks each one against the app's catalog before bundling. A self-built APK is signed with your own key, so it can't install over an official BOAR.

Tested on an 8 GB phone in airplane mode (Oct 22, 2026): install, unpack, and an answer with sources. On 8 GB the 4B is slow (about 30 s before the first word).
