We made a metronome that fits in your pocket because people wanted one. It works like a regular metronome, making beats with sound and animations. But it also flashes lights and vibrates to help you feel the beats. You dont have to focus hard to understand the beats, so you can focus on practicing. Turn on the vibrating mode, put it in your pocket, and use the flashing lights to help you keep the beat, especially when practicing with others. Just remember not to stare at the flashing lights too much.
