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

This update adds a few new features and squashes a few minor bugs that found their way into v2.4.0. Thanks for using PolyNome, and Happy New Year!

What's New?

- Enter any number of notes over any other number (like 5 notes in the space of 7) using the X:Y button at the bottom of the Edit Pattern page.

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.

Great Metronome! It even has Tap Tempo Entry!

This metronome has everything that a drummer could need, including a very easy to use Tap Tempo Entry! Click on the tempo display and a pop-up menu with "tap" at the top shows up. I'm really impressed with the ability to run two different tempo's at the same time. The program is laid out so well, I was able to learn most of the features in just a matter of minutes. It's extremely stable with no lock-up's or crashes, and the tempo's are 100% rock solid! I'm a professional drummer and must have a product that I can count on, I can honestly say that this is a GREAT metronome that you can count on!
