Metronm is a music fitness activity tracker. It relies on a uniquely designed simple multi-track digital metronome with a basic audio recorder to help you work on your daily musical practice. Using your device's motion tracking abilities and combining them with your morphotype values, the app will evaluate the active energy of your musical workout for storage and follow up. Integration to HealthKit lets you easily follow your work and your progress using the Health app. Now you can not only work your best grooves, but also claim to make your music a traceable sport activity. It has four metronomic tracks you can edit / link / mute in order to practice your music. In linked mode first track serves as master tempo and others as subdivisions, but you can have 4 independent tempi running all together. Tapping the logotype lets you tap the tempo. 4 complementary sounds to mark the beat. A simple practice timer to set the duration of your play. A practice mode to preset your favorite practice duration. As simple as it gets. Just play it! ;)
