Line Sketcher is a drawing board for racing lines. Tap Track to load a circuit from the AVB track library (only tracks that have an outline are listed), and its real outline, drawn from the track's coordinates with north at the top, becomes your canvas. If your track is not in the library yet, tap Blank and draw on an empty sheet.
You draw with your finger using five pens, each with one meaning: Braking (red), Apex (amber), Throttle (green), Defending (indigo) and Wet line (blue). A Dashed toggle and a width slider let you tell lines apart, for example a dashed wet line beside the dry one. Undo removes the last stroke and Clear all strokes wipes your drawing after a confirmation.
It is built for the debrief: a coach or parent marks where the driver braked against where they should have, and the driver sees it on the real shape of the circuit. Keeping one colour per idea keeps the sketch readable.
Save a sketch with a title and it is stored on the phone with the track outline included, so it reopens exactly as drawn even with no signal. Open saved sketch lists everything you have kept, and you can delete any of them. Fetching a track from the library needs you to be signed in with a connection; after that, and for blank sheets, the tool works offline. There is no cap on Free. Premium adds PitSync cloud backup for your sketches.
