How Long an App Really Takes to Build: Timelines Nobody Talks About

The project plan said 8 weeks. Simple app, straightforward features. Should be easy, right?

Week 1-2: Planning and design. This went smoothly. Wireframes done. Designs approved.

Week 3-4: Development starts. Everything's on track.

Week 5: First roadblock. The payment integration we planned to use doesn't work the way we expected. Need to find an alternative. That's 3 days lost.

Week 6: Testing reveals bugs. Not small ones—major issues with user authentication. Back to the drawing board.

Week 7: Client wants changes. 'Can we add this feature?' 'Actually, let's remove that one.' Scope creep begins.

Week 8: We're not done. Not even close. We're at week 10 now, and still fixing bugs.

Week 12: Finally launching. But we're already planning updates for things we discovered during testing.

The timeline said 8 weeks. Reality said 12 weeks, plus ongoing maintenance.

That's the timeline nobody talks about. The one with delays, changes, and unexpected problems. Because building software isn't like building a house—you can't see all the problems until you start building.
