This is an interesting little app concept. It’s called Airmov. It is designed to help the user stretch their fingers and loosen them up a bit.
Supposedly it helps avoid problems like carpal tunnel, which is believed to be caused by repetitive motions over time. I’m no doctor, so don’t ask me what I think of any of that. All I know is that typing for too long sucks and stretching does offer a bit of relief.
Check it out at the App Store below. It’s free.:
