Mobile app quotes vary wildly because the term hides three different products: a basic single-platform utility, a cross-platform consumer app with backend, and a native two-platform app with custom design and integrations. The price difference between them in 2026 is roughly 8x. This guide breaks down each path with real numbers, what we actually quote at DevEntia for the same brief done three different ways.
The two-line answer up front: a usable cross-platform MVP runs $25k–$60k. A polished cross-platform v1 with a real backend runs $80k–$180k. A native iOS + Android app with custom design lands $150k–$400k+. Why those bands are wide depends on five specific cost drivers covered below.
The five cost drivers that actually matter
| Driver | Low end | High end |
|---|---|---|
| Platform strategy | Single platform (Android only) | Native iOS + Android |
| Design complexity | Template-based, 8, 10 screens | Custom design system, 30+ screens, animations |
| Backend depth | Firebase / Supabase, no custom logic | Custom backend, real-time, complex business logic |
| Integrations | Stripe + push only | Multiple payment processors, social, AR, ML, IoT |
| Compliance + security | Standard | HIPAA, PCI-DSS, SOC 2, encryption at rest |
Quotes that don't ask about all five are guessing. Walk away.
Native vs cross-platform in 2026
The native-vs-cross-platform debate has shifted decisively in the last three years. React Native and Flutter both now power flagship apps from companies like Meta, Microsoft, Shopify, BMW, and Google itself. The "performance gap" argument holds only in specific edge cases, high-end games, AR-heavy apps, complex camera processing.
| Approach | Cost vs native | When it wins | When native wins |
|---|---|---|---|
| React Native | ~60% of native | Standard apps, fast iteration, JS team | Complex animation, deep OS integration |
| Flutter | ~55, 65% of native | Pixel-perfect designs, smooth animation | Tight ecosystem fit (Apple-only or Android-only audiences) |
| Native (Swift + Kotlin) | 100% | Performance-critical, AR/VR, deep platform features | N/A |
Default to cross-platform unless you have a real reason not to. The cost savings (35, 45%) and time-to-market advantage (often 2x faster) are too valuable to ignore.
Cost breakdown for a polished cross-platform v1
The line-item view of an $110k cross-platform app, a realistic mid-band quote in 2026:
| Line item | Cost (USD) |
|---|---|
| Discovery + technical spec | $5,000–$8,000 |
| UI/UX design (20, 25 screens, design system) | $10,000–$18,000 |
| React Native / Flutter implementation | $28,000–$45,000 |
| Backend API + database | $15,000–$25,000 |
| Auth, push notifications, analytics | $5,000–$8,000 |
| Payment integration (in-app purchase or external) | $4,000–$8,000 |
| Testing on physical devices + automation | $5,000–$10,000 |
| App Store + Play Store submission | $2,000–$3,500 |
| Project management + QA overhead | $8,000–$15,000 |
A polished native build with the same scope typically runs $200k–$280k, most of the additional cost is the second platform's engineering work being duplicated rather than shared.
The hidden cost line items
Three categories quotes routinely understate or omit:
1. App Store and Play Store overhead
- Apple Developer Program: $99/year
- Google Play Developer: $25 one-time
- App review and rejection cycles: 1, 4 weeks of calendar time
- Privacy policy, content rating, age screenshots, non-trivial
Apple's reviewer culture in particular has tightened in 2025, 26. According to Apple's published guidance, apps with weak business models, "spam" categories (yet another to-do app), or insufficient content frequently get rejected. Plan a 4-week buffer between feature-complete and Store launch.
2. Ongoing maintenance after launch
Mobile apps decay faster than web apps because the underlying platforms change yearly. iOS major versions every September, Android every August, plus runtime updates to React Native or Flutter every few months. Annual maintenance budget:
- Cross-platform app: 18, 25% of build cost annually
- Native app: 15, 22% of build cost annually
- Both platforms native: closer to 25, 30% combined
3. Backend infrastructure
The mobile app is the front door. The backend hosting, database, push notification service, file storage, and analytics platform all run continuously. For an app with 10k, 50k MAU, expect $300–$2,000/month in backend costs. Apps doing AI inference (image processing, chat, recommendations) can easily 5x that.
What about no-code / low-code builders?
Tools like FlutterFlow, Draftbit, and Glide have improved enough in 2026 to be a legitimate option for narrow use cases. They genuinely shine for:
- Internal tools for your own team
- MVPs where you'll throw away the code anyway
- Founder-led prototypes to attract first investors
Where they break: complex business logic, performance-sensitive UX, integrations beyond the supported list, anything you'll need to scale beyond 10k users. Most no-code apps that survive end up rewritten, budget for that rewrite when it happens, usually around month 12, 18 post-launch.
The geography effect on app development
Same scope, three regions, real 2026 quotes for the polished v1 above:
| Region | Quote range |
|---|---|
| US/Canada agency | $220,000–$400,000 |
| Western Europe | $150,000–$250,000 |
| Eastern Europe | $90,000–$170,000 |
| South Asia (top-tier) | $70,000–$140,000 |
Cheaper isn't always cheaper, the rework-cost math from our cheap software piece applies just as hard to mobile. The sweet spot for most founders is a senior team in a mid-cost region with a US/EU project lead.
The 2026 mobile usage data founders should know
According to data.ai's State of Mobile 2024, global mobile app downloads passed 257 billion in 2023, with consumer spending hitting $171 billion. Mobile remains the dominant computing platform for consumer attention, but the bar to break through is higher than ever. The median app gets fewer than 100 downloads in its first month.
What this means for budget: spend less on features, more on launch and retention. A great onboarding flow, push notification strategy, and the first-week activation experience matter more than the 47th feature you could build.
How to lower cost without lowering quality
- Pick one platform first. Launch iOS or Android first based on your audience. Add the second after you know which features matter.
- Use a starter kit. Supabase, Clerk, RevenueCat, and similar services remove $15k–$30k of plumbing work.
- Skip animations on v1. The most expensive line item is "make this feel premium." Defer it until you have engagement data telling you which screens deserve the polish.
- Use cross-platform unless you have a hard performance reason not to.
- Outsource design separately. Designers in mid-cost regions can be excellent and the right interface system saves engineering hours.
