Just discovered this app. I love that it allows me to default to LDAC 16/44/quality settings without having to manually fiddle with developer options every time I connect headphones, earbuds, and speakers. I can also toggle between LDAC 16/44/quality and LDAC/16/44/adaptive settings with one click through saved profiles. Paid $4.13 for the premium app. Well worth it for audiophiles who use LDAC.
