A focused MVP typically takes 6-12 weeks from concept to store submission. A medium-complexity app with user accounts and integrations takes 3-5 months. A complex app with AI features, real-time data, or both platforms can take 6-12 months. The biggest variables are feature scope, design complexity, and how ready your requirements are on day one.
Timeline by App Complexity
The clearest way to estimate is by complexity tier. Here is what each usually looks like:
| Complexity | Example | Timeline |
|---|---|---|
| Simple / MVP | Focused feature set, standard UI, one platform | 6-12 weeks |
| Medium | Accounts, API integrations, custom UI, push | 3-5 months |
| Complex | AI/ML, real-time sync, both platforms, IAP | 6-12 months |
The Phases (and How Long Each Takes)
Every app moves through the same stages. Knowing where the time goes helps you plan:
- Discovery & strategy (1-2 weeks) — define the users, core features, and roadmap. Time invested here saves weeks later.
- Design (2-4 weeks) — user flows, UI screens, and a clickable prototype before any code.
- Development (the bulk) — building the app, backend, and integrations. This scales most with feature count.
- Testing & QA (ongoing, plus 1-3 weeks) — device testing, bug fixing, and a beta round via TestFlight or Play testing tracks.
- Store submission & review (a few days to a week) — App Store review runs 1-3 days; Google Play is usually faster.
What Makes an App Take Longer
Some choices add weeks or months. The main ones:
- A custom backend — user accounts, databases, and APIs add design, build, and test time.
- Third-party integrations — payments, maps, social login, and analytics each need wiring and testing.
- AI and real-time features — Core ML, OpenAI, live sync, or chat require specialized work.
- Both platforms — native iOS and Android adds time, though shared design and backend soften it.
- Unclear requirements — the biggest hidden cost. Changing scope mid-build resets timelines.
How to Launch Faster
- Start with an MVP — ship the core, then add based on real feedback instead of guesses.
- Lock the scope early — agree on what is in and out before development starts.
- Use native frameworks — SwiftUI and Jetpack Compose speed up building a polished UI.
- Work with a specialized studio — a team that has shipped 20+ apps moves faster than one learning as it goes.
How Long for Both iOS and Android?
Building both natively does not take twice as long. Strategy, design, and backend are largely shared; only the native app layer is built per platform. Expect a moderate increase over a single-platform timeline — far less than running two separate projects. When your audience is split across platforms, that added time buys you the whole market instead of half of it.

A focused MVP typically takes 6-12 weeks from concept to store submission. A medium-complexity app with user accounts and integrations takes 3-5 months. A complex app with AI features, real-time data, or both platforms can take 6-12 months. The timeline depends on features, design complexity, and how ready your requirements are.
A minimum viable product with a focused feature set usually takes 6-12 weeks: about 1-2 weeks of strategy, 2-4 weeks of design, several weeks of development, then testing and store submission. The tighter your scope, the faster the MVP.
The biggest time drivers are a custom backend, third-party integrations, AI or real-time features, supporting both iOS and Android, heavy custom design, and unclear or changing requirements. Locking scope early is the single best way to protect the timeline.
No, not quite double. Design, strategy, and backend work are largely shared, while the native app layer is built per platform. Building both natively adds time over a single platform, but far less than two separate projects would.
