iPhone — TestFlight beta

1 · Get TestFlight 2 · Join the beta

Install TestFlight (free, by Apple) — first button.
On your iPhone, open the invite and tap Accept → Install.
Open the Fluxer beta and connect it to https://fluxer.systux.xyz (see below), then log in.

Betas expire after 90 days — re-install from the same link when TestFlight prompts you.

Android — beta

Add to Obtainium FCM APK (arm64) UnifiedPush APK (arm64)

Recommended: install Obtainium, tap Add to Obtainium above (FCM build for normal phones; degoogled phones need the OSS build — full list at fluxer.app/download/android). Obtainium then installs and updates it for you.
Or sideload: the outline buttons above (most phones since 2016 need arm64; degoogled/GrapheneOS takes UnifiedPush + separate setup). Repeat per update.
Open the app and connect it to https://fluxer.systux.xyz (see below), then log in.

Verify an APK signature

Release builds are signed with this SHA-256 certificate fingerprint — check it before installing a file you got elsewhere:

91:E4:98:E1:B8:A6:C8:BA:99:41:5E:DB:29:78:29:6B:6C:58:BA:A5:E2:D2:A6:49:CE:C6:2D:A7:A8:29:C7:BC

What the script does

Adds the official pkgs.fluxer.com repository (key fingerprint is verified before import).
Installs the desktop app.
Detects Wayland/X11 + NVIDIA/Intel/AMD and writes GPU-aware Chromium flags.
Points the app at your instance via a .desktop override — no system files touched.

Piping to bash? Read the script first — every installer is plain bash in /scripts/. Advanced knobs: DESKTOP_ONLY=1, ASSUME_YES=1, GPU=, SESSION=, EXTRA_FLAGS=.
