My experience with students that have used various learning software has been mixed.

They're not good for absolute beginners because it can't give you feedback on the bad physical habits that lead to repetitive strain injuries, or just make it hard to play.

Once you're past that point, you're usually far enough to find a tab or chord sheet and figure it out.

For a motivated intermediate level student there can be value in the smooth difficulty progression and forced introduction of new concepts, but that's a pretty small window where they add value.
