This app works BEAUTIFULLY for something that’s been out for, what, maybe two weeks? There are some minor issues that are actively being worked out, but the core functionality is SOLID. The classic text version from the website is embedded into the app, if you prefer that workflow, but for me the appeal is the piano roll. It’s got all the things you’d expect: tempo, metronome, MIDI import as of the recent update (1.4.0 as of me writing this). It’s got custom time signatures too but I haven’t fiddled around with that enough to really rate it (sorry ;;)
The dev is very responsive, if you come to him with an issue he’ll either help you fix it or push out a patch that fixes it within the next few days. I assume that as the app grows, this responsiveness will diminish, but that’s just a downside of (seemingly) being a one man team.
I’m excited to see where this project goes!!!
