Online app estimate - how much does an app cost?

An online app estimate is a quick, preliminary calculation of a project’s cost and time based on its scope and complexity. At KrMob you fill in a short form and instantly - in seconds - see an indicative cost and timeline, with no waiting for a salesperson and no commitment. Thanks to Flutter (one codebase for iOS, Android, web and desktop) and working without project-manager overhead, our estimates are usually lower than the market average.

Indicative ranges (net)

Simple app (1 platform, basic features) from ~12,000 PLN
MVP for iOS + Android (Flutter) ~18,000-28,000 PLN
App with backend, admin panel and payments ~30,000-60,000 PLN
Advanced / AI / integrations / enterprise from 60,000 PLN

Net amounts, indicative (+ VAT). The estimator above gives a tailored figure for your project.

What does the price of an app depend on? +

Mainly the number of platforms (iOS, Android, web, desktop), the number and complexity of screens and features, the need for a backend and admin panel, integrations (payments, maps, APIs, AI), UI/UX design and the delivery deadline.

How long does app development take? +

A simple app takes 4-8 weeks, an MVP 2-4 months, and a larger project 4-6 months. We count in working days with a start-up buffer.

Why is a KrMob estimate lower than the market? +

We build with Flutter - one codebase instead of separate iOS and Android - and work as a tight team without project-manager overhead. You pay for code, not for structure.

Is the online estimate binding? +

No - it is a preliminary, indicative estimate, not a contract. We confirm the final amount after a short conversation about the details. The estimate is free and non-binding.

Do I have to sign an NDA before the estimate? +

No. At the start you can skip the NDA and go straight to the form - you can sign it later if you wish. For the estimate itself we only need a short project description and an email address; no company details or tax ID required.
