Mobile App

Lyftr has a native mobile app so you can log workouts at the gym, straight from your phone — talking to your server.

Android

1. Download the latest signed APK from the Releases page.
2. Open the .apk on your phone and allow “install from unknown sources” if prompted.
3. Launch Lyftr and enter your server URL when asked.

Side-loaded builds don’t auto-update

When a new release drops, download and install it over the old one. Store builds with auto-update are on the roadmap.

Pointing the app at your server

The app connects to your self-hosted instance, so it needs a URL it can actually reach. Use https://. Everything below assumes that; plain HTTP is covered after, as the exception it should be.

• Point it at a real hostname over HTTPS — see HTTPS & Reverse Proxy. This works from anywhere, not just your home network. A LAN-only hostname can still get a genuine, publicly-trusted certificate via DNS-01, with no ports open to the internet.
• localhost won’t work from a phone — it refers to the phone itself. Use a hostname or your server’s LAN IP.
• Running your own CA instead? Install it on the phone — the app trusts the device’s user-installed CA store. See HTTPS & Reverse Proxy.
• CORS_ORIGIN only matters for the web app (see Configuration). Native apps send no Origin header and are never subject to CORS.

If you must use plain HTTP

http://192.168.1.10:8080 works — Android blocks unencrypted traffic by default and the app opts back in, so a bare docker compose install is usable. If it fails outright, update to the latest build.

What plain HTTP costs you

Nothing is encrypted. Every request carries your login token in the clear, so anyone else on that network can read it and stay signed in as you, and a captured token can’t be revoked. The app shows an amber Not encrypted marker while this is in effect.

Full detail and the fix: HTTPS & Reverse Proxy. Treat plain HTTP as a temporary state, not a setup.

iOS

Planned. Apple doesn’t allow side-loading, so iOS will ship via TestFlight / the App Store once the Apple Developer account is set up. Watch the repo for updates.
