The Exodus Report is really good, I would also recommend https://f-droid.org/packages/io.github.muntashirakon.AppManager/ . you can install an app, then check it with App Manager, before first run, which will often find more trackers than Exodus will
Edit: and https://themarkup.org/blacklight for finding trackers in websites
