Free and fully functional! No buying anything in app or BS like that... I accidentally posted in the wrong section when my other apps were released, and I felt bad so I decided to make a free one for shred and crazy rock guitar type soloing and letcha all know about it. It's kind of a 'beta' and needs some polishing and stuff, but hopefully you enjoy it! The next ones will be definitely a step up.
