PolyNome is used by the world's top musicians including Peter Erskine, Virgil Donati, Chris Coleman, Vinnie Colaiuta, Dave Weckl, Dennis Chambers and Will Lee.

“PolyNome is great for teaching, practicing and rehearsing. The rhythmic and the subdivision possibilities are endless. Plus, this is the only metronome I’ve used that you can actually LEARN from. Simply brilliant.”

Peter Erskine (Steely Dan, Weather Report, Kate Bush)

Great app

I’ve been playing the guitar for a year and I started practicing creating grooves for my strumming and other studies. It helps me a lot and it makes me improve as well. I think it’s an amazing app!!

Fantastic App, but it’s too busy

I think Polynome is a fantastic metronome which gives a world of possibilities in terms of options. Anyway, in many cases I found it too busy, and that thing created confusion in me.
I hope that in the future the App will have a “lighter” graphic with more understable menu. The idea of the summary is very cool but there are too many logs e stuff like that. Anyway, my message has the only purpose to help to get this app to an “higher ground”, because, I repeat, it’s fantastic. I hope that my not super skilled English didn’t create confusion.

Please update for iPhone 12 mini

There is a screen size issue with the new iPhone 12 mini. I’ll give 5 stars if you resolve it.
EDIT: They resolved the issue, so ⭐️⭐️⭐️⭐️⭐️
The best metronome EVER!

Risposta dello sviluppatore ,

Thanks for leaving a review. Please could you contact me at and I’ll make sure this is resolved.
If the iPhone 12 mini has a notch at the top, try going to Preferences -> Pan,Vol,Mixer, and scroll to the bottom of the page and turn on “Adjust layout for notch”
