How long does it take to build an app?
A well-scoped MVP takes 8 to 14 weeks. A full-featured product takes 4 to 7 months. An enterprise platform with real integrations takes 6 to 12 months. Anyone promising a real app in two weeks is describing a prototype or a template.
Those ranges assume a dedicated small team, decisions made within a day or two, and no mid-project change of direction. Every one of those assumptions is where real projects slip.
Where the weeks actually go
- Discovery (8–12%). Requirements, user flows, technical architecture. Skipping it does not save time, it moves the cost into rework later.
- Design (15–25%). Wireframes, visual design and a clickable prototype. If you already have final designs, this collapses to a handover week.
- Development (50–60%). The largest block, and the one most affected by team size.
- QA (20–25% of development). Real device testing, edge cases, performance. Cutting QA is the single most expensive saving in software.
- Launch (1–2.5 weeks). Store submission, review and release. Apple review is usually 24–48 hours but a rejection costs you a cycle.
Why a bigger team does not mean a proportionally faster app
Doubling the team does not halve the schedule. Coordination overhead grows, and some work is inherently sequential — you cannot build the checkout before the cart exists. Moving from one developer to a three-person pod is transformative. Moving from three to six buys maybe 25% more speed for double the cost.
The reliable way to compress a schedule is to reduce scope, not add people. Try dropping the feature slider by three and watch the timeline move more than a team upgrade achieves. The feature estimator shows exactly which ones are costing you weeks.
What causes projects to slip
In our experience, delays come from four places, and none of them are the code: slow feedback (a design review that takes ten days), undocumented third-party systems (the ERP integration nobody has the spec for), content (product copy and images that arrive late), and scope added mid-build.
You control three of those four. Naming one decision-maker, agreeing a 48-hour feedback turnaround, and having your content ready before development starts routinely saves more calendar time than any technical decision.
