If you are wondering how long it takes to build an app, the honest answer is a few weeks for a simple MVP and a few months for a full product. The range is wide because "an app" can mean a single-feature MVP or a full platform with accounts and payments behind it. The timeline follows the scope. Here is what actually sets it.
What sets the timeline
A few things decide how long it takes. The first is how many features you need, because every screen and flow is more to design and test. The second is the backend. If your app stores data or takes payments, someone has to build the server and admin behind it, and that is often larger than the screens people see. The third is design. A custom interface takes longer than a template, and it is usually worth it.
Rough timelines, by type
Treat these as ballparks, not promises. A focused MVP with one core feature can be ready in a few weeks, and our fastest reached the app stores in under 21 days. A standard business app with a backend and several features usually takes a couple of months. A larger product or a marketplace takes longer, and we give you a real timeline once we know the scope.
What speeds it up
You can move faster without cutting quality. The biggest lever is scope, because the smaller the first version, the sooner it ships. Clear decisions help too, since a project slows down most when it is waiting on answers. And building in React Native means one codebase for iPhone and Android, so you are not paying to build the app twice.
Do not forget the app store review
One step founders forget is the store review. After the app is built, Apple and Google review it before it goes live, which usually takes a few days and occasionally longer. We handle the submission and the back-and-forth, but it is worth knowing that "done building" and "live in the store" are a few days apart.
How we work
We give you a real timeline before we start, tied to the scope we agree together, and we keep you updated as we go. If speed matters, we will tell you honestly what a smaller first version could ship in, and what is better left for later.
