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 2.3.8

Thank you for using PolyNome.
I'm constantly working to improve the app and add new features. If you have time to leave a review, they really help. Thanks in advance!
New features in this version:

Drumline sounds added! Plus some new snares, brush hits, a kick, and "In" and "Out" voice sounds.

● Improved Sound Picker:
Tap "Met 1" or "Met 2" label in the mixer to bring up the Sound Picker. You'll see category buttons to quickly jump to the section you want. New sounds have a "New" label on them until you've heard them once.

● Improved Labelling:
It's now super quick and easy to assign multiple labels to one or more Presets or Playlists. Simply tap the + Labels button to assign labels.
Begin typing the name of the label you want to find. If it doesn't exist you can tap the top row to create and assign it.
Tap the Filter button to filter on Labels. You can now filter on multiple labels at once (e.g. Band, A minor, Ballad)

● Improved Charts:
You can now zoom in on charts and swipe left and right to get a closer look at your stats. The interface has been cleaned up and you can easily view them in portrait mode.

● Playlist Merge improvements:
You can select multiple items in the Playlist Manager and “Merge To New” from the Actions menu. This will create a new Playlist containing the contents of your selected Playlists in the order that you selected them. This allows you to easily create clicks for different songs and then merge them into a Setlist. The new addition is that a title row will be added above the contents of each Playlist to help you navigate. See the What’s New video in the Inbox for more details.

● Minor changes:
- When importing Presets or Playlists they'll be labelled with "!Last Import" so you can quickly find them.
- Imported items will no longer have the ‘inbox’ or ‘book’ icons appended to them, but they will be permanently labelled with those tags.
- When viewing an open goal (e.g. 30 mins/day) with a target time (e.g. 100 hours) you'll see the estimated completion date above the stats.
- Long Preset and Playlist names are now truncated in the middle.
- Fixed bug where the Cumulative Timer in the Practice Event display would continue to count up even while PolyNome was stopped.

If you find any problems, or have any questions, don't hesitate to get in touch via the help page or the website.

I'd love to see what you're creating with PolyNome. On iOS 11 devices you can record the screen (google it). If you post recordings of your creations to Instagram or Facebook and tag PolyNome or @PolyNomeApp I'll share the best ones.

Thanks again!

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,

Awesome Program!

If you’re a up and coming drummer taking lessons or even an advanced drummer this is a must have!! I cannot believe it took me this long to find it and make a decision on buying the app. So many possibilities on here it’s crazy. I use it on my iphone currently and will eventually move to an ipad but it is addicting once you start digging into it. I plan on using this for my gig this Saturday for the first time and I am excited to use it. The idea of adding swing to the song will make it feel lime it should. Kudos to you all for this wonderful app!! Best $21 and change I’ve spent in a while!

Developer Response ,

Thanks for the great review. I'm pleased you like the app. More useful features coming in the next version!

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.
