Appearance
Day, Dawn, Dusk, and Dark. Same layout, different light. The button advances to the next theme.
Plans
Hobby gets a generated *.mycodedapp.com URL. Pro ($19/month) picks the subdomain. Business ($49/month) attaches a domain you own via CNAME to cname.mycodedapp.com.
Drop an app first, then upgrade it here or from the app page.
