Ten Kettles announces BeatMirror: Beat detector for rhythm training 1.0, their new tempo-detection and training app for iOS devices. BeatMirror analyzes drum beats in real-time, displaying a drummer's tempo and other statistics as an aid to help the musician stay on the beat. Drummers just pick a target tempo and then start drumming. The app helps build internal rhythm skills, by indicating whether the beat is too fast or too slow. BeatMirror: Beat detector for rhythm training 1.0 is $2.99 and can be downloaded from iTunes.
