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 2.4.6

2.4.6 brings some great new features and improvements to PolyNome.

The summary is below. Check "What's New In 2.4.6" in the in-app Help for further details.

- MIDI device control, including Bluetooth MIDI pedals (in Preferences - > Remote Devices)

- Import Setlists from Tempo and Tempo Advance!
Share them from the Tempo/Tempo Advance app and email them to yourself. Then tap on the file in the email and choose to open with PolyNome.

- Copy multiple Playlist items to your Preset Library (for re-use in other Playlists) by selecting them in Edit mode and choosing "Copy Missing To Preset Library" from the Actions menu.
They'll be labelled with the name of the Playlist so you can easily filter on them.

- On the Playlist page, if you select an item and choose "Add Count In" from the + menu, it now adds a named count in with voice counting before the selected item.

- You can set Playlist items to SKIP when reached. This is great for Count Ins that you only want to hear the first time the Playlist loops. Set this by tapping the gear button of the relevant item, or by selecting multiple items and choosing "AutoAdvance Options" from the Actions menu.

- When Met 2 is empty, there's a new option when you tap on it to "Copy Met 1 to Met 2". Useful if you've entered a rhythm and you need more than 2 lines of sounds.
- When in a Playlist and you tap the "rep" button on the main screen, it will loop the current pattern.
- Prompt about unsaved changes when entering Playlist Manager or Creating New preset to stop you accidentally losing changes.
- Taller flashing blocks at the top of the screen.

Enjoy these new features.

Paradigm Shifting Metronome & Metronomic Learning Tool

This app can change your life on any instrument. 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.

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.

Best metronome app I’ve ever seen

For me, the price that you pay for this app is worth every single cent. It is very versatile. For one thing, the variety of sounds included in this app makes it so that you can always find a sound that you can hear over what you’re playing. For another, the ability to play two independent patterns allows for the creation of complex polyrhythms or really intricate drum beats. Additionally, the playlist function allows you to create large, non-repetitive passages. These three features have been invaluable to me when learning percussion parts because it allows me to seamlessly switch between meters. On a few occasions, have even programmed whole sections of my part so I can play along slowly. The interface does take a little getting used to, especially on smaller screens, but once you get used to it it’s very easy to use. By far the best metronome app I have found.

Developer Response ,

Thanks for the review, and for pointing out the issue with remembering the inc/dec state. That will be fixed in the next update.
Please contact me via the help page in the app to discuss the other issue - I'd like to get to the bottom of that.
