FAQ
App cost questions buyers ask first
Is this a fixed-price quote?
No. It is a transparent planning range from GMI’s published 2026 guide. A fixed price requires validated scope, integrations, constraints and ownership.
Why not calculate a price from feature count?
Feature count hides the main cost drivers: API readiness, business rules, integrations, offline synchronisation, compliance, QA and release risk.
Does React Native reduce cost?
React Native provides one codebase for iOS and Android. It reduces duplicated platform work, but discovery, UX, backend, QA, store release and maintenance still need budget.
What should I prepare for a useful estimate?
Share the app type, required systems, current backend, critical deadline, compliance needs and who owns decisions on your side.
