A web app MVP, scoped in writing and built in about four weeks

You need a first version real users can sign in to and pay for, not a slide deck. It starts with a $450 written scoping that turns your idea into screens, data and a fixed price. Then the app is built, deployed to your own accounts, and handed over with the code.

Pay $450 for Scoping

Scoping $450 in 3 business days, ending in a fixed build quote. Builds start from $6,000 and take about 4 weeks.

No call needed. Questions go to contact@app369.com; we reply by email, usually within one business day.

This fits when

  • You have validated demand and need a working product
  • The app runs in a browser: a portal, a dashboard, a marketplace or an internal tool
  • You need sign-in, roles and payments from day one
  • You want a fixed price instead of an open-ended hourly bill

Questions before you pay

Why does a build start at $6,000?
That covers a small MVP: sign-in, a few core flows and one or two integrations. The scoping sets the exact fixed price for yours before you commit.
Do I have to go ahead with the build?
No. The written scope is yours to keep and use with any developer.
Can it become a mobile app later?
Yes. Native or Flutter mobile apps are quoted separately, and the backend built for the web app can usually serve them too.
Do I need a call before I pay?
No. The scope, price and delivery time are on this page, and everything happens in writing. If you want to talk live, calls cost $100 per 15 minutes, paid upfront.
Who owns what you deliver?
You do. The code, videos and files delivered under this offer belong to you once paid.
