How Long Does It Take to Build a Mobile App in 2026?

"How long does it take to build an app?" is right up there with "how much does it cost?" And like cost, the honest answer is a huge range — from a few minutes to well over a year. The deciding factor is which path you take. Here's a realistic 2026 breakdown.

The short answer

ApproachTypical timeline No-code (convert your website)Minutes to a few days Freelancers (simple custom app)1–3 months Agency / dev team (complex app)3–12+ months If you already have a website, you're at the fast end of that table — you don't need to build from scratch.

What affects the timeline

• Complexity — more features and custom screens mean more build time.
• Platforms — building iOS and Android natively from scratch roughly doubles the work.
• Design — custom UX takes time to design, test and refine.
• Content readiness — if your website already exists, most of the work is done.
• Revisions — feedback loops with developers stretch timelines fast.

Timeline: custom development

A custom app moves through discovery, design, development, testing and submission. Even a "simple" custom app rarely ships in under a month with a freelancer, and complex products run many months with a team — plus ongoing maintenance afterwards. For most businesses this is the slow, expensive path. We cover the money side in our app cost guide.

Timeline: no-code / converted apps

This is where the timeline collapses. With a no-code converter you paste your website URL, customise the app, preview it on your phone, and generate signed iOS and Android builds — often the same day. There's no separate iOS and Android development, no design sprints, no back-and-forth. See the full process in our guide to turning a website into an app.

Don't forget store review

Whatever path you choose, the app stores add their own time. Apple's review typically takes one to three days; Google Play is usually faster. This is unavoidable and applies to everyone — so the real variable you control is the build, not the review. (And no, you don't need a Mac for the iOS side — here's how to publish without one.)

FAQ

What's the fastest way to get an app?

Converting an existing website with a no-code platform — you can have store-ready builds in minutes, then just wait for store review.

Why do custom apps take so long?

They're designed and coded from scratch for two platforms, then tested and revised — each stage adds weeks or months.

How long is App Store review in 2026?

Usually one to three days for Apple and often faster for Google Play, though it can vary with demand and your app's content.
