Riffly Play turns a guitar tab into a practice session. The score plays back with a cursor that follows along, you can slow it down, loop the bar that keeps falling apart, and mute the guitar to play the part yourself. When you are ready, record your take: the app listens through your microphone, lines up what you played against the score and marks every note as perfect, off or missed.
What you can do
Play any tab back with a synthesized band and a cursor that follows the score.
Slow the tempo down while a passage is hard, then bring it back up.
Loop a difficult bar and repeat it until it is clean.
Mute the guitar track and play the part yourself over the backing.
Record your take and get every note marked perfect, off or missed.
Listen back to your own recording lined up with the tablature.
How practice works
Open a tab and listen to it at full speed.
Set a tempo you can actually play at and loop the hard bars.
Hit record — a count-in gives you the beat — and play along.
Read the note-by-note analysis and repeat what you missed.
