Describe it the way you would tell a friend. Attach a photo of the form you fill in by hand, the spreadsheet, the message you send ten times a day. No brief, no jargon.
Your app appears on screen as it is built. Click through it at phone, tablet and desktop widths. Ask for changes in plain words. Every turn ends with a working app: the AI runs it, sees what broke, and puts it right before it replies.
Two copies. One your customers use. One only you see. Try every change on the private one, then bring it to the real one with one press. Your customers never see a half-finished change, every version is kept, and a copy of the site and its data is taken before each one goes out.
No subscription. The site stays up for the server charge alone.
A day like this one, written as an example. Your Monday, your words, your Apptain.
Describe it. See a first version today. Hand it to an Apptain whenever you like.
