How long does it take to build an app?

TL;DR: There's no single answer, it depends heavily on which stack you use and how complex your idea is. As a rough starting point: a simple web app can often launch in 2-6 weeks, a native mobile app typically takes 4-8 weeks, and a no-code build usually takes 1-3 months because you're learning the tool while building. Complexity, not the calendar, is what actually moves these numbers.

Why does the stack change the timeline so much?

A web app has no app-store review step and the simplest deployment path, so it tends to reach real users fastest. A native mobile app adds native build tooling and app-store review on top of the same core development work. A no-code build adds the time needed for you personally to learn the platform, on top of the build itself.

What actually makes a build take longer?

The number of distinct screens and workflows, whether payments are involved, how many user roles and permission levels exist, and how many third-party integrations you need all add real time, regardless of which stack you pick. A simple single-purpose tool is faster to build than a multi-sided marketplace in any stack.

Does hiring an AI-assisted developer change the timeline?

Yes, meaningfully. Compared to a traditional development timeline, AI-assisted tools speed up how quickly a developer can implement a given feature, the scope of what you're asking for doesn't shrink, but the time to build it typically does.

What's a realistic first milestone?

A working first version that covers your core flow end to end, not every feature you can imagine. Founders who insist on shipping everything at once are usually the ones whose timeline stretches the most; a focused first release you can put in front of real users is almost always the faster, better path.
