How Long Does It Take to Build an App?

A realistic idea-to-store timeline for a cross-platform app depends on scope, but there's a real shape to it. Here's how the phases break down and what stretches them.

The phases every build goes through

Almost every app moves through the same stages: discovery and scope, design, development, testing, and store submission. The total time is set by how much lives inside each stage, not by any single magic number.

A lean MVP moves through these faster than a feature-rich v1 with accounts, payments, and a backend — same phases, very different durations.

  • Discovery and scoping: features, flows, and priorities
  • UI/UX design: screens and a prototype
  • Development: the shared cross-platform build
  • Testing and beta: real devices and fixes
  • Store submission and review: Apple and Google

What stretches or shortens the timeline

The clearest schedule-killers are scope creep, slow feedback, and unready dependencies — waiting on your content, a third-party API, or hardware firmware. The fastest projects have a tight feature list and a decision-maker who reviews quickly.

Cross-platform helps here too: building both platforms from one codebase is faster than sequencing two native builds.

  • A tight, prioritized feature list keeps it fast
  • Fast review and decisions on your side
  • Ready content, assets, and API access up front
  • Cross-platform ships both stores in one track
  • Scope creep and mid-build changes add the most time
  • App-store review adds days you can't fully control

Frequently asked questions

How fast can we launch something?

An MVP with a focused feature set launches meaningfully sooner than a full build — that's the whole point of starting lean. The exact timeline depends on your scope, which we'll map in a free consultation before committing to dates.

How long does app-store review take?

Apple and Google reviews usually take from a day to a few days, but it's not fully in anyone's control, and a rejection means a fix-and-resubmit cycle. We build a buffer for review into the plan rather than promising an exact launch day.

Can you build iOS and Android at the same time?

Yes — that's a core reason to go cross-platform. Both platforms come from one codebase in a single development track, instead of two sequential native builds, which shortens the overall timeline.
