Awesome potential!

This is easily one of the best free metronomes on the App Store. Its minimalist aesthetic is also very pleasing. I would like to see an addition of hotkeys to make simply switching time signatures easier for those who don’t have as complex understandings of rhythms. However the customization allowed by the interface makes this app very appealing over other metronome apps; most that allow for similar customization are behind paywalls. Overall, I’m very pleased with this app and optimistic for its future!

Awesome potential

I will echo another review I’ve seen: it’s got so much potential and a lot of fun to work with. Only thing I wish it had is subdivisions that could be divided at equal speeds (for example a 2+2+3 8th note subdivision for a 7/8 meter). Other than that I’m excited to see how the app will progress!

Very promising start after 2 weeks!

Nice clean UI and very flexible. The sound set is not to my taste, but sound prefs are promised. My main ask is a way to change the number of steps in a column without changing the timing of the steps — this will make it more intuitive to set up subdivisions like a 4/4 beat divided into 3-3-2.
