A web app MVP starts from $6,000. The first step is a $450 written scoping; the build is then quoted at a fixed price and starts only with your yes. Mobile apps and bigger projects are quoted separately the same way. How the MVP Sprint works.
A fixed offer is a set scope at one price, paid in full before work starts. The same feature inside a custom build is estimated as a range, because its scope depends on your project. To compare, the fixed-price price study lists what other sellers publish for this kind of work.
Start from the base for your platform, add the features you need, add design if you want it, and you have a range. The final number is a written fixed quote after scoping, so it can land above or below the estimate when your scope turns out different from what you described. Hosting and third-party service costs are not included.

Questions
Fixed-price offers are paid in full before work starts. Web App MVP Sprints start with the $450 scoping; the build is then quoted in writing, with its payment schedule, and starts only with your yes. Consultations are paid upfront. All payments are in USD.
A web app MVP starts from $6,000. As a rough estimate, a web app version one runs $6,000 to $9,000, a mobile app for iOS and Android from one Flutter codebase $9,000 to $14,000, and a second platform adds 45% to 60%. Features and design add to that, for example Stripe from $950, an AI feature from $2,500 and each integration from $1,200. The firm number is a written fixed quote after scoping.
Yes. The ranges on this page are estimates. The instant quote gives a range in a minute, and a scoping turns it into a fixed price and timeline for your project.
Maintenance retainers range from $500 to $5,000 per month depending on app complexity and support tier. Basic covers bug fixes, security updates and email support during business hours (Monday to Friday, Eastern Time). Professional adds feature enhancements, crash and uptime monitoring, priority handling of critical issues and monthly reports. Enterprise plans are custom-scoped.
Each fixed-price offer lists its delivery time on its page. A Web App MVP Sprint takes about 4 weeks from the signed quote, and the exact timeline is in the quote. Building iOS and Android from one Flutter codebase avoids doing the work twice.
