ScreenChalk is an app for drawing on top of your home videos like a sportscaster or tv commentator.

It's great for coaches, athletes, dancers, models, presenters, public speakers, salespeople, and anyone else who benefits from seeing what they're doing: film your technique, your team, or your routine, move the video into the app, then play it back (fast, normal, or slo-mo, on the device or on your tv). If you see something you could improve -- a misplaced arm, a nervous tic, or an awkward angle -- use one of the markers to draw something pointing out the issue, then email it or save it as a snapshot.

It's like you see on TV: if you load your movies into the app, you can open them from within the app, play them back, and draw on top of your movies with colored markers.

If you have one of the video-out cables you can use the app with a tv or projector: in this mode you control video playback and add annotations from the device while playing the video -- and your annotations -- on the big screen. This is great for larger audiences (or when you just want a bigger screen). The app has a virtual laser pointer feature that's particular

Suggested Uses:

- coaches: film your players, watch the film with them, point out areas for improvement
- coaches: watch film of your opponents, point out weak spots and opportunities
- presenters, salespeople, etc.: film your routines, check for poor posture, nervous habits, etc.

It's also fun for kids: put some family movies in it, then let your kids add smiley faces, funny haircuts, and so on.
