How Much Does It Cost to Build a Mobile App in 2026?
A custom mobile app typically costs $40,000–$150,000 to build in 2026. A lean single-platform MVP can land around $40k; a polished cross-platform product with a backend, integrations, and post-launch iteration runs $120k and up. Scope, platform, and team model drive the number far more than any hourly rate.
What actually drives mobile app development cost?
The single biggest lever is scope — how many features earn a place in version one. Every extra screen, integration, and edge case compounds design, engineering, and QA time, and the total climbs faster than most teams expect.
After scope, four factors move the number the most:
- Platform — iOS only, Android only, or both. Cross-platform (React Native, Expo) shares one codebase; fully native (Swift, Kotlin) duplicates part of the build.
- Design complexity — custom motion, bespoke components, and a real design system cost more than an off-the-shelf UI kit, but they're what make an app feel native-quality.
- Backend and integrations — auth, payments, real-time sync, and third-party APIs add engineering and infrastructure work behind the screens.
- Team model — an offshore team of juniors and a senior embedded product team produce very different results at very different rates.
Typical mobile app cost by type (2026)
| App type | Timeline | Typical cost |
|---|---|---|
| Simple MVP (one platform) | 6–10 weeks | $40k–$70k |
| Cross-platform MVP | 8–14 weeks | $60k–$110k |
| Complex product (backend + integrations) | 12–20 weeks | $120k–$250k+ |
| Ongoing iteration (retainer) | Monthly | from $8k / month |
Ranges assume a senior product team building to US/EU quality. Rates vary by region and seniority.
iOS, Android, or cross-platform — which is cheaper?
For most early-stage products, cross-platform is the cheaper path to a real audience: one React Native or Expo codebase ships to both stores and typically saves 30–40% versus building two fully native apps.
Go native (Swift or Kotlin) when performance, complex animation, or deep hardware access is core to the experience — a fitness tracker, a camera app, a game. The right answer is a scoping decision, not a default.
How to reduce app development cost without gutting quality
You don't cut cost by cutting corners on the two or three screens users actually touch. You cut it by being ruthless about everything else.
- Scope the MVP to the smallest thing that delivers real value — defer the rest to a funded v2.
- Prototype before you build: an on-device prototype surfaces the expensive mistakes while they're still cheap to fix.
- Choose cross-platform unless a native-only capability is central to the product.
- Phase the roadmap so spend follows traction, not a 60-page spec written before launch.
How long does it take to build a mobile app?
Most MVPs reach the App Store in 8–16 weeks. The first two weeks should produce an interactive, on-device prototype you can put in front of real users — well before the bulk of the budget is committed.
A larger product with a custom backend and several integrations runs 4–6 months to a polished 1.0, then settles into a monthly iteration cadence.
Frequently asked
Is it cheaper to build one app for both iOS and Android?
Usually, yes. A single cross-platform codebase (React Native or Expo) ships to both stores and typically saves 30–40% versus building two fully native apps — the right choice for most early-stage products.
What is the cheapest way to launch a mobile app?
A focused single-platform MVP — the two or three screens that deliver real value — validated with a prototype first. That keeps a first launch in the $40k–$70k range instead of six figures.
Do app development costs include maintenance?
No. Build cost is separate from ongoing work — updates, OS releases, new features, and monitoring. Most teams budget a monthly retainer (often from $8k) once the app is live.
