What syncs between the mobile app and the web?

Scripts and folders sync both ways (you can create, edit, and delete scripts on the phone), along with your custom vocabulary, team vocabulary, pronunciation hints, and two prompter settings: Reading speed (WPM) and Voice tracking strength. The overlay sliders (size, width, transparency, reading line, text size, mirror, video quality) are per device. Recordings stay in the phone's gallery and never upload, and team-library scripts don't show on the phone. The phone needs an internet connection to load scripts and to track your voice.
