I actually use Tenuto for this purpose - it includes this specific exercise, but also a plethora of other exercises for guitar along with others (staff, key memorization, piano) and utilities like cord construction. Best money I’ve spent on an app.

I really like Tenuto as well. What I'm building is intended to be a deeper and more polished version of just the guitar (and eventually ear training) parts of Tenuto.
