Mobile app development cost in Serbia 2026 — realistic prices and timelines

The question 'how much does mobile app development cost' has no single answer — it's like asking 'how much does a car cost'. It depends on what you want. But there are factors that directly determine the price: feature complexity (login system, payment, real-time chat, map, camera — each adds time and cost), number of platforms (iOS + Android together or separately), need for backend/API, design (custom from scratch vs using a Design System), and third-party integrations (payment gateway, push notifications, analytics).

Flutter is currently the most popular choice for cross-platform mobile development and the reason is clear: one codebase for iOS and Android, excellent performance, Google backing and a growing ecosystem. Flutter project cost is 30–40% lower than developing two native apps because you write the code once. React Native is an alternative (Facebook/Meta), a slightly older ecosystem, similar price. Native Swift (iOS) + Kotlin (Android) are the most expensive but give maximum performance — justified only for games, AR apps or apps that intensively use hardware.

MVP (Minimum Viable Product) is the right start for most projects: implement only the core features that solve the primary problem, launch, measure what users actually use, then iteratively add more. An MVP of 2–3 months of development reveals whether the idea works before spending a full product budget. Many clients come with a list of 50 features — MVP helps identify which 5–10 are truly critical for launch.

Hidden costs agencies don't mention enough: Apple Developer Program (€99/year for iOS publishing), Google Play Console (€25 one-time), backend hosting (AWS, Firebase, Supabase — from €20/month for small apps to €200+ for larger ones), push notification service, analytics platform, annual updates for new OS versions (iOS and Android change APIs every year), and customer support. These costs accumulate — calculate them before making a decision.

Approximate prices for the Serbian market in 2026: simple app (login, list, detail, contact, no complex backend) — from €5,000 to €10,000 for Flutter MVP. Medium complexity app (payment, chat, map, offline support, custom backend) — €15,000 to €35,000. Complex platform (marketplace, real-time features, ML/AI, multiple user roles) — €40,000+. These prices are for Serbian agencies with a quality portfolio — you can find cheaper, but then also calculate the risk and quality.
