iPhone: If you’re on the move a lot, controlling the music on your iPhone by tapping buttons isn’t always easy. Swysh is an iPhone app that lets you use simple motion gestures to switch between songs.
With Swysh, you can flick your phone to the left or right to switch between songs, or flick it down to play or pause. There’s also a pocket mode so you don’t accidentally switch between tracks just because you’re walking. You can adjust the sensitivity of those gestures, but even still, I occasionally had trouble getting Swysh to recognize movement, usually when I was trying to pause the music. Regardless, while Swysh might sound a little silly, it’s actually pretty convenient when you’re driving, especially if your car doesn’t support controlling your music from the stereo itself. Right now, it only works with the music app, but third-party support is supposedly on the way.
