I can hear the music playing, but when I tap my phone I don’t hear the feedback sounds.
To use the Motion Trainer, you must have the ringer audible on your iPhone. This means you must not have the mute switch (on the top left side of your iPhone) set to “mute” and you must have the ringer volume higher than zero. Also, note that the Motion Trainer has a switch to turn it on and off when the music is playing. Make sure the switch is set to “on” if you are trying to tap your device to the music.
Will Quick Rhythm work on my Android, BlackBerry, Palm, Windows, or other smartphone?
No, right now Quick Rhythm is only available for the Apple iPhone and iPod Touch. It will also run on the Apple iPad, although the Motion Trainer is difficult to use due to the size of the tablet. In the future, we plan to support additional smartphones and devices.
