Yes, you can use iRp to tailor a specific exercise for a student, have iRp generate a pdf and send the student home with a paper chord chart.

Or... (and) since *everyone* now probably has access to a "smart-device" of some sort, encourage your students to use iRp to download charts you've made specifically for them from your "sandbox" and use them in the app.
The iRp player beats the socks off a metronome.
Charts are instantly transposable.
The player's practice feature can easily and seamlessly slowly speed up a looped section (or entire chart) during practice.

The list (and the beat) goes on...
