Dr. Betotte

While this option is more expensive than the others on this list, it definitely deserves a mention because of its robust package of features. It costs just under $10 and is compatible with both Apple and Android devices.

This product takes its inspiration from the well-known Dr. Beat Metronome line. Musicians who are familiar with Dr. Beat devices will feel right at home in this app. The customization options in this app are unreal. You can subdivide the beat in any way you can imagine. Use straight or swing styles, and with independent volume controls for each beat subdivision, you can really fine-tune your playing.

Also notable are the coach functions with their gradual tempo changes. This is an ideal tool when you’re trying to perfect a particularly tricky section and don’t want to mess around with metronome settings.
