We highly recommend Chordify Premium, but using Chordify for free is also possible. You won't get all the great features like capo hints or file uploads, but you can play along to a (limited) set of songs. When you choose to use the free version of Chordify you will see advertisements and we might ask you to subscribe to Chordify Premium every now and then.
To check out everything that Chordify Premium has to offer, check out the Chordify Premium page.
If you are interested in trying out Chordify Premium for free, be sure to check out our Chordify Premium channel.
