Use this guide to actually setup all the things needed to run Flow Pilot: https://github.com/phr00t/flowpilot/wiki/Simplified-%22Tarball%22-Flow-Pilot-Install-Process
I recommend using the "android-release.apk", which is the latest "stable" build with the DA model (the best I've tried).
"android-release-northdakota" is if you try a North Dakota commit which has a newer model, but frankly it sucks.
"always-onroad" is useful for debugging without panda hardware. You will need to run modelparsed in the background (selfdrive/modeld dir I think) in termux.
