Many ask me this question: “How Long Does It Take to Build an App With Vibe Coding?” Honest answer: it depends on what you’re building. But probably faster than you think.
Here’s what the timeline actually looks like based on my own experience shipping 6 apps in 6 months.
A Simple App: Hours to Days
A focused app with 3-5 features, no complex backend, no user accounts — you can have a working version in a few hours.
My first app took one afternoon. It did one thing. It worked. I shipped it.
The Cursor hackathon app — an AAC communication tool for people with aphasia — took 3 hours to build from scratch. It had voice cloning, pre-recorded phrases, and a functional UI. Three hours, solo, no preparation.
Simple scope plus clear vision equals fast execution.
A Medium App: Days to Two Weeks
Something with user accounts, a database, multiple screens, and real design — figure on a few days of focused building to get to a working MVP.
This isn’t 8 hours a day of grinding. It’s a few sessions of building, testing, iterating. The AI does the heavy lifting. You’re steering, reviewing, adjusting.
The limiting factor at this stage usually isn’t the tool — it’s decision fatigue. What should this screen look like. What happens when a user does X. What do I cut to ship faster. Those decisions take time regardless of how good your tools are.
A Complex App: Weeks to Months
Anything with complex logic, multiple user types, integrations with external services, or App Store submission — budget weeks, not days.
Not because the building is slow. Because there are layers you don’t see coming. Edge cases. App Store review. Design polish. Testing on real devices. Copy. Onboarding flow.
My iOS apps each took 2-6 weeks from first prompt to App Store approval. The building itself was fast. Everything around the building took time.
What Actually Slows You Down
It’s almost never the coding. AI handles that fast. What slows people down:
Unclear vision. The vaguer your idea, the more you’ll rebuild the same thing five times. Spend 30 minutes writing a clear brief before you open any tool. It saves days.
Scope creep. You start with a simple tracker and three weeks later you’re building a full SaaS platform. Cut features ruthlessly. Ship the small version first.
Perfectionism. Waiting until it looks perfect before showing anyone. Ship when it works, not when it’s beautiful. Beauty comes in version 2.
Context switching. Building three apps at once and finishing none of them. One project at a time until it ships.
App Store review. If you’re going to iOS, factor in 1-7 days for Apple’s review process. It’s out of your hands once you submit.
A Realistic Timeline for a First App
If you’re brand new to vibe coding and building your first real project:
Week 1 is learning the tool and building something small and throwaway. You’ll spend more time figuring out the environment than building the actual app. That’s fine and expected.
Week 2 is where things click. You start your real project. You iterate faster. You stop second-guessing every decision.
Week 3-4 you’re polishing, testing, fixing edge cases, writing copy, preparing to launch.
First app shipped: 3-4 weeks for most people who show up consistently.
Second app: half the time. Third app: half again. The learning curve drops fast once you’ve completed one full build cycle.
The Number That Actually Matters
Not how long it takes to build. How long it takes to ship.
Building and shipping are different things. A lot of people build forever and ship never. Set a deadline before you start. “This goes live in two weeks no matter what.” Then cut whatever you need to cut to hit that date.
The fastest builders I know aren’t the most technical. They’re the most decisive. They make calls fast, cut scope without guilt, and get comfortable with good enough.
Six apps in six months wasn’t because I’m fast. It was because I shipped each one before I talked myself out of it.
