User reviews

Issue fixed!

Many thanks to the developer! Very responsive, and fixed the problem in an update.

Update: Downgrade issue fixed

Previously gave the app three stars because the update/redesign resulted in not being able to restore the previous purchase. They fixed this in the latest update, and all is well now—thanks!!

Serious tool

The polyrhythm features in this app are amazing. No other metronome comes close

App was great before iOS 11 and 64-bit apps

This app was great and easy to use for creating sequences before iOS 11. The app temporarily didn’t work when iOS 11 began running 64-bit apps. The developer eventually updated the app, but it doesn’t work the same anymore. I wish there was a website or video with directions for creating sequences with multiple meters. The developer needs to release a page with detailed instructions with the latest updates for creating more complicated sequences. You’re better off looking for another app for creating rhythms and extended metronomes with meter changes for practicing.

Response from developer

Hi, Thanks for your review. The website now contains tutorial videos and a downloadable pdf user manual.

Doesn’t work, no support, con

No support (developer website is dead). Makes hideous electronic squeals and awful digital drones. Clicks don’t work. No instructions. Total con. Thanks for nothing. How about my money back, Apple?
