How Long Does It Take to Build a Custom App?
Typical timelines for an MVP, a business app and a larger platform.
A small MVP typically takes 6 to 10 weeks, a business application with a backend 3 to 6 months, and a larger platform 6 months or more. Discovery and design usually take 2 to 4 weeks before development starts.
- Clear requirements shorten every later stage.
- Integrations and approvals (such as app store review) add calendar time.
- Working software is usually visible within the first few weeks.
What are the stages of building an app?
- Discovery (1–2 weeks): requirements, users, integrations, scope and estimate.
- Design (1–3 weeks): user flows and interface designs for the key screens.
- Build (4 weeks to several months): development in short iterations with demos.
- Launch (1–2 weeks): testing, release to the web or app stores, monitoring.
Typical timelines by project size
| Project | Typical timeline |
|---|---|
| MVP with one core feature | 6–10 weeks |
| Business app with backend and admin | 3–6 months |
| Platform with several apps and integrations | 6+ months |
What slows a project down?
Unclear or changing requirements, slow feedback on designs and demos, third-party integrations with poor documentation, and content or data that arrives late.

Frequently asked questions
Can you speed up development by adding more developers?
Only up to a point. Small, focused teams are usually faster than large ones on projects of this size.
