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.

What people are saying about PolyNome:
Peter Erskine (Steely Dan, Weather Report, Steps Ahead, Kate Bush):
“PolyNome is great for teaching, practicing and rehearsing. Tempo input by way of the number pad is a terrific feature, and the subdivision possibilities are endless. Plus, this is the only metronome I’ve used that you can actually LEARN from. Simple and brilliant: simply brilliant.”

Will Lee says...
"Wow! Polynome is a brilliant tool for drummers and any musician! It allows you to understand precisely what subdivisions among bars of time feel like, teaches you the drum rudiments, and so much more. I love "time check" where it'll leave bars of silence in between bars of click to see if your groove stays in time. One of the best apps for your toolkit!"

What's New

Version 2.3.6

I'm excited to release this update. It includes massive improvements to the Practice Log, including the ability to set Goals! It also includes under-the-hood speed and battery improvements.

I'm always striving to make PolyNome the best music tool on the App Store.

Nag, nag, nag.


It's like we're married! How many nags does one app need. In-app messages...not enough. Push notifications...not enough. Pop ups as soon as the app opens...not enough. Need a login to get the things that the app works with...not enough. Pop up to ask if it should track my practice time...not enough. Popup to ask me to rate the app...not enough. There can always be more. Why, when I'm paying for an app, does it need so many things to get my attention? I just want a metronome. I guess two physical metronomes that just click would be less annoying than all of the nags. If you're going to nag to get a's going to be a good review. My preferences are already set to not get any notifications...and yet, here I am talking about all of these nags. I wonder what it's like to have ADD and have this app. You're not likely to even get to practice.

It sounds like you're very unhappy.

I realise there are quite a few notifications the first few times you use the app. They're there to explain various features and confirm whether or not you want to receive notifications. I know it can seem a bit much at first, but they stop - I promise.

I hope you've settled in with PolyNome and didn't file for divorce.

You can always contact me through the app if you have questions.

All the best,

Edited review: Still too much for me BUT


I really appreciated the specialized one-to-One attention that I got from Joe but still think that the app is way more than I need personally. I DO like that it’s a pseudo rhythm composer similar to The Rhythm Calculator I mentioned before.

Knee jerk purchase for me. I bought the most expensive version thinking that maybe there was some of the same functionality as an app called rhythm calculator that the developers abandoned.

There are features in this app that I will probably never use and it just seems like an overload of information in one simple concept like a metronome. I want to like it and at least get my moneys worth but probably won’t use it much if at all.

Developer Response

Hi, thanks for leaving a review. I understand that it can seem intimidating at first since there is a bit of learning curve. However, I'm certain I can help you grow to love it.
Please email me at and give me a chance to change your mind.
I look forward to hearing from you.

Ridiculously awesome - more than a great metronome

Ghent did

I've bought most of the popular other metronome apps. It was a waste of money. This app goes sooo much. A great metronome. Can down load rudiments, including the sticking. Which is great for teacher/student organization. Automatically keeps track of practice logs. Can increase tempo over time, which I love. All is dynamically controlled and a pretty short learning curve and there's great instructional videos. Very very happy with this app.

I downloaded it today and am learning all the many bells and whistles. Two things I might have missed, but I don't think they are there is I don't think this is cloud supported so iPad and iPhone don't sync. Also, I would like to have the option of brighter visual cues. Again, these features might exist and I don't see them.

I don't write a lot of reviews, especially long ones. Very
Well developed.
