No 3rd: B5 (4 4 2 2) leaves the 3rd out, so it backs B major, mixolydian, dorian and minor tunes alike.

Tuning GDAE: G D A E, low to high. The octave mandolin uses the same tuning, so these shapes fit it too.

The link can’t set the tuning: the app starts on the Irish bouzouki in GDAD. Choose GDAE once in its Settings and it remembers.
