Great Meteonome

Love the simple and straight forward implementation. Please, make it were you can create and name presets instead of overwriting the defaults. I am completely happy with everything else about this application. I get most users want to throw everything and the kitchen sink into one application but I really hope this app just builds on improving on what already exists instead of trying to attach the api for external applications etc. Keep it simple and clean like it should be and already is. Thank you

Fantastic metronome/beat machine

I really love this app. It has a minimal and easy UX that allows you to get straight to the good stuff quickly. The ability to change the sounds for up to four different pips, not only makes it more sonically pleasing than most metronomes, it also means it doubles as a great beat machine than can easily program far more complex rhythms than many iOS beat machines available. One bug I’ve noticed - the fourth pip (dark gray), which starts out default as silent, only changes sound when you scroll to another sound setting, then exit/re-enter the app. I also just discovered that whatever changes you make with a preset selected, overwrite the preset! This is definitely NOT desirable behavior and I just lost several programmed patterns due to this (not a bug per se but still annoying). Please change this so you only write to a preset when selecting to save and give it a name, to avoid accidental destructive edits.

Feature requests for the developer: please add Ableton Link/midi clock sync capability, and consider compatibility with AudioBus, AudioShare, and other iOS pro audio apps! In addition, the ability to upload user sounds as sources. Would make this already quite potent tool, absolutely formidable.

Four stars for now due to the bug, preset handling, and lack of inter-app integration, but I hope to come back and make it five stars in the future. Overall I’m highly impressed with Impulse!!

Awesome potential!

This is easily one of the best free metronomes on the App Store. Its minimalist aesthetic is also very pleasing. I would like to see an addition of hotkeys to make simply switching time signatures easier for those who don’t have as complex understandings of rhythms. However the customization allowed by the interface makes this app very appealing over other metronome apps; most that allow for similar customization are behind paywalls. Overall, I’m very pleased with this app and optimistic for its future!
