Your profile lives in the app under Settings → Profile. It's quick to set up and worth doing — your favorite genre group helps set your initial Dig view.
What you can set:
Display Name — the name that represents you. Your login username lives on the Account tab, not here.
Profile picture — upload an image from your device.
City — where you're based.
Favorite Genre Group — choose the one broad sound you spin most.
On a bare Dig visit, your favorite genre group is used as the starting filter when you don't already have a remembered filter. Once you choose a different Dig filter, your last-used choice takes precedence.
You're never boxed in — every genre group is still available from Dig, and you can change your favorite genre group at any time.
Edit any field and save when you're done.
