This app is free for today so I thought it might be handy to one or two people. Here’s the app’s description:
Most iPhone piano apps are tough to make real music on. With Applichord Mini, anyone with two thumbs can be a piano player!
Inspired by a music teacher’s autoharp, if you know the chords to a song, you can accompany anyone easily.
If you want to play a D major chord, you play the “D” key with one thumb and hit the “maj” button with the other. The chords for most popular songs can be found with a simple google search.
Also great for song writers who want to experiment with new progressions but might not have the knowledge or theory background for playing more complex chords like a Bmin13 or an F#min7b5.
