v2.2.3-beta

Columba 2.2.3-beta

Installation

Pick a backend, then download the APK matching your device's CPU architecture.

• Python backend, RECOMMENDED — ships Mark Qvist's official python reference implementations of Reticulum and LXMF via Chaquopy.
• Kotlin backend — ships Torlando's EXPERIMENTAL, AI-GENERATED native reticulum-kt / lxmf-kt / lxst-kt stack.

The python version is highly recommended. The kotlin version is a work in progress, and is not yet verified to be completely safe.
The kotlin version may yield better battery life depending on your device, and comes in a smaller apk due to not requiring a python runtime.

Python backend (official-rns-py)

APK	Architecture	Devices
columba-2.2.3-beta-official-rns-py-armeabi-v7a.apk	armeabi-v7a	Older 32-bit ARM phones & tablets
columba-2.2.3-beta-official-rns-py-arm64-v8a.apk	arm64-v8a	Most modern Android phones & tablets
columba-2.2.3-beta-official-rns-py-x86_64.apk	x86_64	Chromebooks, emulators, some tablets
columba-2.2.3-beta-official-rns-py-universal.apk	All	Universal fallback (larger download)

Kotlin backend (EXPERIMENTAL-reticulum-kt)

APK	Architecture	Devices
columba-2.2.3-beta-EXPERIMENTAL-reticulum-kt-armeabi-v7a.apk	armeabi-v7a	Older 32-bit ARM phones & tablets
columba-2.2.3-beta-EXPERIMENTAL-reticulum-kt-arm64-v8a.apk	arm64-v8a	Most modern Android phones & tablets
columba-2.2.3-beta-EXPERIMENTAL-reticulum-kt-x86_64.apk	x86_64	Chromebooks, emulators, some tablets
columba-2.2.3-beta-EXPERIMENTAL-reticulum-kt-universal.apk	All	Universal fallback (larger download)

Telemetry variants:
Each APK above also has a -no-sentry variant without crash reporting for maximum privacy — append -no-sentry to any download link above (e.g. the most common builds: Python arm64-v8a no-sentry · Kotlin arm64-v8a no-sentry). Sentry collects stack traces when Columba encounters errors
and provides helpful information to the developer to improve Columba, but is hosted at sentry.io, and is thus not the maximum privacy option.

Not sure which to pick? Most Android phones use arm64-v8a. If unsure, use the universal APK.
