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."

What’s New

Version 2.5.2

Happy New Year!

Version 2.5.2 of PolyNome adds the option to set the text size for Playlists. This is really handy if you're playing live and want a clear view of your setlist!

It also fixes issues where some of the tutorial videos did not play. If you're still getting your head around PolyNome, you might want to revisit those.

Bug Fixes:
- Fixed bug with incorrect AutoCounting when a group of notes started with a rest
- Fixed bug where individual 16th notes didn't react to swing setting
- Fixed bug where using AirTurn to change tempo would crash the app
- Fixed bug where tempo was incorrect if using dotted quarter note as the base

Please let me know if you find any bugs by contacting me through the Help page, or emailing

Paradigm Shifting Metronome & Metronomic Learning Tool

This app will change your life. On any instrument, it is the perfect companion and there’s no metronome that even comes close. It has any choice of sounds, subdivision overlay faders, two separate rhythm entries plus with two Lines each that can reflect the selected sticking from multiple sounds in each limb, polyrhtmic and counting full screen visuals, online public community library of presets and playlists, playlists that cycle presets and sub presets, setlists, the list goes on, on. The bottom line is if you’re in anyway interested in the world of rhythm, this app is worth every cent. We have a lot to be grateful for from drummer Joe Crabtree, it’s sole developer. Have a new idea or an issue with the app? He’ll hear you out and address it. This app is almost perfect as is, albeit with a relative learning curve that pays dividends (aided by joe’s vast video tutorials linked within the app and beyond). This app will only continue to grow in scope and sweetened layout ergonomics. With this tool, our learning is only limited by our imagination and discipline. Thanks Joe.

Thank you for the kind words and glowing review. PolyNome really is my baby, and I’m constantly working to add new features and fine tune the existing ones. I’m so pleased that you’re making good use of it.

If you're reading the reviews

Just get the app already. It is quite nice, really. If you just need a basic metronome, it does that. If you want something more, it does that too. Very well. It's had a considerable amount of forethought put into every aspect. From ease of user interface for nubes to intricately involved options for the advanced time-keeping applications. I took all of my old metronome apps off of my new iPhone and installed them on my old iPhone and shot it with my .38 then destroyed what was left of it with hydrochloric acid. As should you. This is the most well maintained, constantly updated, content rich application in the history (and more than likely, the future) of the  app store. It surely is in the Gueniss Book of World Records. Or it should be. When the cyborgenic aliens finally DO annihilate us, this is the one singular human thing they’ll find worthy of not destroying. That’s assuming they don’t chance upon Heroin first, which destroys everything.

Used to love this app

Haven’t been a fan since it was rewritten, and everyone had to pay for the Pro version a second time. I feel like maybe the devs are trying to do too much with it. The interface seems cumbersome. It definitely is not something to use when you just need a simple click, as you have to program in a rhythm before the metronome will even work. Who’s ever heard of a metronome that you can’t just hit Play and go? Also, the app has an inbox? That’s annoying. Is there a way to avoid receiving messages unless they’re of vital importance?

I originally got PolyNome because I wasn’t entirely happy with Tempo Advance’s weird interface. I was perfectly happy with the original version, and I wish the devs would have kept it available with occasional compatibility updates as necessary. The new version makes me consider going back to Tempo Advance. At least it’s equally usable/fast whether you need a simple click or a complex polyrhythm. PolyNome is not worth using unless you’re doing something complex, and have the time to program it.

Developer Response ,

Thanks for leaving a review. I appreciate the feedback.
I’d like to clarify a few things.

- Nobody should have had to pay for Pro a second time. It’s a once only purchase. Please email me at if you feel like you’ve been charged twice.

- When you load PolyNome it has a basic quarter note click as the default. You can hit play and you have a regular metronome. You can also use the faders in the mixer to add in 8th notes or 16th notes like a Dr Beat. If you’ve lost that default you can tap the disk button in the top right to load it and then again to reset it.

- There’s an option in preferences that will load the default when you reopen the app (instead of loading whatever you were last working on). If you use that it’ll always be ready to play a regular click when you launch.

- The inbox allows me to notify you of updates, and send free presets, etc. I’m sorry you find it annoying.

I would genuinely love to speak to you on Skype to find out what kind of things you’d like to do, and how I can help you do them more easily, or tweak future versions of the app to make it more useable.

Please email me at if you’d be happy to chat.

All the best,
