Almost every "how much does an app cost" article online lies through generality: "$10K–$500K depending on complexity!" Useless. Here is the actual breakdown for what drives mobile app costs in 2026, with honest ranges by app type.
What actually drives cost
- Number of unique screens (more screens → more design + dev hours).
- Backend complexity (an app that just consumes existing APIs is cheap; one that needs a custom backend doubles the bill).
- Auth complexity (email/password = easy; SSO / biometrics / multi-tenant = harder).
- Real-time features (chat, live updates, presence) — these add infrastructure cost forever.
- Native platform features (camera, AR, NFC, HealthKit) — each one is custom integration.
- Native vs cross-platform (React Native is ~60–70% the cost of going native on both platforms).
- Designer involvement — a good designer pays for itself; a bad one rebuilds the app twice.
Realistic ranges by app type (build only, year 1)
MVP / "validate the idea" — $25K–$60K
One platform (iOS or Android, not both). 8–15 screens. Simple auth, basic backend (Firebase or Supabase), no exotic features. Good for testing demand. 6–10 weeks to ship.
Standard cross-platform app — $60K–$150K
React Native or Flutter, both stores. 20–35 screens. Custom backend, push notifications, analytics, in-app purchases. The shape of most consumer apps in 2026. 12–20 weeks.
Native + complex platform features — $120K–$300K
Native iOS (Swift) + native Android (Kotlin). Camera/AR features, offline sync, complex animations. Health/fitness, AR commerce, hardware-integrated apps. 20–30 weeks for v1.
Platform / multi-app product — $300K–$700K+
Multiple apps (consumer + admin + partner), shared backend, SSO, rich admin tooling, real-time features. Year-1 bill for a serious B2B mobile play.
Hidden costs
- App Store + Play Store accounts: $99/year (Apple) + $25 one-time (Google).
- Third-party services: Firebase, Mixpanel, Sentry, Stripe — typically $200–$2K/month at launch scale.
- Annual OS-update maintenance: budget 10–20% of build cost per year. Apps left unmaintained break within 12 months.
- App Store review iterations: 1–3 rejection rounds is normal. Add a week of buffer.
- Localization: each language is ~5–10% of the build cost depending on scope.
Native vs React Native vs Flutter
In 2026: React Native and Flutter are both production-grade. We default to React Native unless there is a specific reason for native (deep platform features, gaming-grade performance). The cost savings of cross-platform are real but smaller than they look once you account for platform-specific tweaking.
Native is justified when (a) a single platform dominates your user base, (b) the app needs hardware-level features cross-platform frameworks struggle with, or (c) the team has long-term native expertise.
Where most projects overspend
- Building too many features for v1. Cut to the smallest version that delivers value.
- Designing without engineering input. The Figma is gorgeous; the implementation cost is 3x.
- Hiring an offshore team without senior oversight. Cheap by the hour, expensive in rework.
- Skipping CI/CD. Manual deploys eat 1–2 days/week forever.
- Underestimating maintenance. Year 2 is real money.
How we scope mobile app projects
Our mobile app development engagements always start with a 1–2 week paid scoping phase: a written technical plan, named features per phase, and a phased estimate. Most clients save more than the scoping cost in avoided rework.
If you have an idea or a Figma file and want to know what it actually takes to ship, that is the place to start.
