Mobile App Development Services
PerfectionGeeks provides end-to-end mobile app development services: product strategy, UX and UI design, native iOS and Android development, cross-platform apps with Flutter and React Native, backend and API development, AI features, testing, app store launch and ongoing support. We build consumer, business and enterprise apps for startups and established companies across 15+ industries. A focused app or MVP typically costs $15,000–$40,000 and launches in 8–12 weeks; a full-featured app costs $40,000–$100,000.
- Start with the smallest version that proves value to users; add features after launch based on real usage.
- Cross-platform (Flutter or React Native) suits most apps; choose native for heavy graphics, AR or deep device features.
- Plan security from day one: OWASP's Mobile Application Security Verification Standard (MASVS) is a widely used checklist.
- Accessibility is now a legal requirement for many apps in the EU under the European Accessibility Act, which applies from June 2025.
- Typical cost: $15K–$40K for a simple app or MVP, $40K–$100K for a full-featured app, $100K–$250K+ for complex or enterprise apps.

Native vs Cross-Platform: Which Should You Choose?
Most of our MVPs use Flutter or React Native, adding native modules only where needed.
| Comparison | Native (Swift and Kotlin) | Flutter | React Native |
|---|---|---|---|
| Codebases | Two | One | One |
| Performance | Best | Very good | Very good for most apps |
| Best for | Graphics-heavy apps, AR, advanced device features, single-platform apps | Custom-designed UI that looks identical on both platforms | Teams with React skills and apps that use native components |
| Relative cost | Highest | Lower | Lower |
Features Most Apps Need

How Much Does Mobile App Development Cost?
These are planning ranges; your estimate depends on final scope. Native apps for both platforms usually cost more than one cross-platform app. Running costs include hosting, third-party services, developer accounts and maintenance of roughly 15–20% of build cost per year.Cost drivers: number of features and user types, platforms, design complexity, backend and integrations, security and compliance, AI features and team location.
| App complexity | What is included | Typical cost | Timeline |
|---|---|---|---|
| Simple app or MVP | Core features, sign-up, basic admin, one cross-platform app | $15,000–$40,000 | 8–12 weeks |
| Full-featured app | Payments, real-time features, integrations, analytics, web admin | $40,000–$100,000 | 3–6 months |
| Complex or enterprise app | Multiple user types, complex integrations, high security, offline sync, scale | $100,000–$250,000+ | 6–12 months |
