How Long Does It Take to Build an App From Scratch?
Realistic timelines for mobile and web app development — from MVP to production — and what causes delays.
Short answer: a simple app takes 6–8 weeks. Apps with a backend, payments, or real-time features take 3–6 months. Enterprise systems can take a year or more.
Realistic estimates
- Simple app (a few screens, no login): 6–8 weeks.
- Standard app (accounts, APIs, push): 3–4 months.
- Complex app (payments, real-time, IoT, AI): 4–6 months.
- Web application: 6–12 weeks for a dashboard or SaaS product, depending on scope.
Why apps take longer than expected
- Backend scope — most of the time goes into servers, data, and security, not the screens.
- App-store review — publishing itself can take days per release.
- Testing — real-device QA on many screen sizes and OS versions takes time.
- Requirement changes — scope changes are the #1 cause of delay.
How to ship faster
Start with an MVP, freeze scope for the first release, and treat "nice-to-have" features as a phase two. A technical lead will protect the timeline by pushing back on scope creep.
