How long does it take to build an app or website?

Right after "how much does it cost", the next thing clients search is "how long does it take". Timelines are as misunderstood as budgets — a "simple app" can take three weeks or three months depending on what is inside it. Here are honest, real-world timelines and the things that quietly add weeks.

Realistic timelines by project type

These assume clear requirements and reasonably prompt feedback. AI-accelerated teams typically land at the shorter end because boilerplate that used to take weeks now takes days — leaving engineers to focus on the logic that makes your product unique.

Marketing / business website: 1–3 weeks
Website with accounts + payments or a small admin: 3–6 weeks
Mobile app MVP (Android + iOS, one codebase): 6–12 weeks
Two-sided platform (customer + partner apps + admin + backend): 3–6 months

What actually slows a project down

Unclear or shifting requirements — the number-one cause of delay
Slow feedback and approvals from the client side
App Store review (Apple can take days; plan for it)
Third-party dependencies (payment KYC, API access, content you must supply)
"Just one more feature" added mid-build without re-planning

How to launch faster without cutting corners

Speed comes from scope discipline, not from rushing engineering. Launch a focused first version that does one thing extremely well, get it in front of real users, and add features from real feedback. A tight MVP that ships in 8 weeks beats a "complete" product that never launches.
