The add-on and Android app synchronize the current frame, start/end range, and scene FPS. Changes made in one side are reflected in the other during a connected session.
Set the scene range and FPS before recording. Use the app Timeline and Playback controls to scrub, edit values, and play forward or reverse. Blender remains the authoritative scene timeline.
Some builds expose custom smooth playback controls for reviewing camera motion. Use them only after a bake is complete, and stop playback before changing recording state or control mode.
