Send a few sentences about the app, who it's for and roughly when you'd like it live. I reply within one business day with next steps and, if it's a fit, a time for a free 20-minute call.
The one-line idea, who will use it, which platforms you care about (iPhone, Android, Watch, TV), whether it will charge money and how, and any existing website, video library or brand assets it needs to connect to. Don't worry about being technical; that's my job.
A free 20-minute call, then a written scope with a fixed price and timeline within two business days. No obligation, and you can take the scope to anyone else if you like.
