Some time ago I looked for a piano app - something I can use on the go to harmonize with, try some chords, or just play. I wasn't happy with anything that I found, so I made my own:<p>- It's a progressive web app. Add it to homescreen to avoid multi-touch scroll shenanigans<p>- just a few hundred KB<p>- made using web audio, vanilla JS, SVG.<p>- no annoying popups<p>Please enjoy and let me know how you like it.
