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.

You can jump to the Practice Log for a specific Preset or Playlist by tapping the new Practice Log button on the right of each item.
If you have a goal set, the button will be orange.
(You can tap the "Labels" button and filter on the bar chart label to see only Presets that have goals set.)

You can now add and edit Practice Events within the Practice Log:
- swipe to the furthest right screen and tap the + button to add an event for the current Preset.
- to edit an event, tap and hold it, or tap the Edit button and select the event you want to edit.

You can now set Goals for Presets, Playlists, and even Labels.

You set goals on the Practice Log page. Tap where it says "vs Previous Period ▼" and choose "Set a Goal"

- specify how long you want to practice each day/week/month for an open goal.
- enter a target time (eg. 100 hours) and a deadline date, and you'll see how much practice you need to do today in order to hit your target.
- enter a target tempo and deadline date and you'll see the bpm increase you need to hit each day.

Use the Daily Journal to make general notes about your practice session, or to plan what you want to work on in the future.
Access it from the menu, or from the Practice Event Editor (tap the left of the 3 buttons under Play to toggle the Practice Event Editor).

A calendar view shows you which days you have journal entries for. Tap an empty date to add an entry for that date.

A new star label has been added for convenience.

Great practice tool


I'm an intermediate/enthusiast drummer, and not pro, so I have a shorter, structured practice time. This app helps me structure my practice, track my progress, and really think about the notes I need to play when I'm focusing on my technique. As a metronome it's great, of course, but it's more of a transcription and journaling tool than it might appear - though it's difficult to use initially, as you become accustomed to the app you'll find it anticipates your needs. I've loved using it, and the playlist function - as well as the information it returns on each practice session - has been a great boon to efficient but thoughtful practice.

2.3 brings a few really nice features that make it easier to change views and sounds. There’s also a focus on polyrhythms which has always been one of this metronome’s strengths, not that I’m even practicing fives over four or anything. This summer I made really good use of the logging feature, which is really busy and probably too granular but gives me a super useful graph of my time. It’s like a metronome and a habit-tracking app. Always great.

Invaluable practice tool


This app is amazing for those of us that take the time to learn it. There are many different tutorials built in, and I found that once I went through those I truly was able to use the app to its full potential. It does everything I want it to do and more. This is not a metronome for people who simply want an on/ off click track. Instead, this is a metronome for practicing musicians trying to refine skills. Great tool for improving your timing, also. I love the customizable silent count features. Buy it and go through the tutorials!

Amazing Metronome App

Victory Transformation

This is hands down the best drumming, practicing and writing tool for drummers that I have found!!! Also can be used for click track creation. The possibilities are endless. Also, the creator, Joe, is a drummer and is personally involved. He responds to every question I send him and does his best to explain things to you. I have been programming Hot for Teacher to share with the drumming community because you can do that as well. Joe made a video explaining the best way to program it for me. Amazing app. Definitely worth it!! Get it, you won't ever regret getting this!!!
