FAQ

Frequently asked questions

01How much does mobile app development cost?

An MVP starts at $9,000 for 8-12 weeks, a business app at $13,000, a full product with a backend at $18,000. The exact estimate is free after a briefing: price depends on the number of flows, integrations and backend requirements.

02Cross-platform or native — which should we choose?

For most tasks — cross-platform (Flutter/React Native): one team, one codebase, half the cost of ownership. Native (Swift/Kotlin) is for where it pays off: heavy graphics, device-specific features, maximum performance. At the briefing we'll honestly price both.

03Do you publish the app to the App Store and Google Play?

Yes, publication is part of the project: developer accounts, store page materials, privacy and permissions, passing review. Store rejections are our problem: we carry the app to publication — it's part of the job, not an "extra service".

04What happens to the app after release?

An app is a living product: new iOS and Android versions, crash monitoring, library updates. We offer SLA support and metric-driven growth: analytics shows which features users actually need. The code and accounts are yours.

05We already have a website — can the app work with it?

Yes, it's the typical scenario: the app connects to your website and back office via an API — catalog, orders, accounts and prices live in one system. No API yet? We'll design and build one — integrations are our profile work.
