Introduction
"It depends" is the correct answer to this question and also the most useless one, so let's skip it. Below is what actually drives mobile app development cost, with real ranges, so you can budget before a discovery call instead of getting a number that feels arbitrary.
These ranges reflect what a small, senior-heavy team (like ours) charges for quality work — not the lowest bid you'll find on a freelance marketplace, and not enterprise consultancy rates either.
The Three Cost Tiers
Tier 1: Simple MVP (single platform, core flow only)
A single core feature set, one platform (iOS or Android, or cross-platform via React Native/Flutter), standard auth, and a handful of screens.
Range: $8,000 – $18,000 | Timeline: 6-10 weeks
This is validation-stage work — proving the core loop works before you raise, before you scale, before you add every feature on your wishlist.
Tier 2: Full-Featured App (cross-platform, backend, integrations)
Real backend infrastructure, push notifications, payment integration, admin panel, third-party API integrations (maps, analytics, CRM), and both iOS + Android from one codebase.
Range: $18,000 – $45,000 | Timeline: 3-5 months
This is where most funded startups land for their initial production release.
Tier 3: Complex/Custom Platform
Real-time features (chat, live tracking, multiplayer logic), custom backend architecture, heavy third-party integrations, marketplace or multi-sided logic, or native performance requirements that rule out cross-platform frameworks.
Range: $45,000 – $120,000+ | Timeline: 5-9+ months
What Actually Moves the Number
| Factor | Impact on cost |
|---|---|
| Native (Swift/Kotlin) vs. cross-platform (React Native/Flutter) | Native can run 30-50% higher due to building twice |
| Backend complexity (simple CRUD vs. real-time/event-driven) | One of the biggest cost drivers — often underestimated |
| Third-party integrations (payments, maps, AI, CRM) | Each integration adds design + testing time, not just API calls |
| Design maturity (wireframes only vs. full UI/UX system) | Skipping proper UX design early costs more in rework later |
| Team seniority | Junior teams are cheaper per hour, slower and buggier per feature — the real cost shows up in the timeline and QA cycles |
The Mistake That Inflates Everyone's Budget
Founders consistently under-scope the backend and over-scope the feature list. A beautifully designed app with 15 features and a fragile backend will cost more to fix post-launch than it would have cost to build a tighter 5-feature MVP on solid infrastructure in the first place.
Our actual advice on every discovery call: cut the feature list before you cut the backend budget.
A Realistic MVP Budget Breakdown
For a Tier 1 MVP around $12,000, here's roughly where that goes:
- UI/UX design: 15-20%
- Frontend development: 30-35%
- Backend + infrastructure: 30-35%
- QA and testing: 10-15%
- Project management/buffer: 5-10%
Any quote that skips QA and buffer entirely is either underpricing (and will ask for more later) or planning to ship something that breaks in production.
What We'd Tell You Before You Spend Anything
If you're pre-funding or bootstrapped, don't start with Tier 2 scope. Start with the smallest version that proves your core assumption, get it in front of real users, and let actual usage data — not your own assumptions — decide what Tier 2 should include.
If you want an honest number for your specific idea instead of a range, that's a faster conversation than more research — tell us the core flow and we'll tell you which tier it actually falls into, and why.
