User reviews

Great start but it needs work

I was messing around with the app and as an acid piano learner I think this is a great beginning, but you need to work on the Audio functions. if I rapidly click on a chord, instead and unpausing it rapidly, it will just play multiple of the same audio files at the same time and completely glitch out for a solid second.

Incredibly useful tool still but it needs work.

Response from developer

Hi Collinc09, Thank you so much for your honest feedback. We want to make Keytionary the optimal experience for learning chords and voicings so the audio playback is key. We are pushing an update to the app that will address the chords interrupting another and glitching as you described. We plan to keep iterating on this feature to make it as seamless as possible moving forward. Thank you again for the feedback and we are glad to hear you find the tool useful.
