How Long Does It Take to Build an App?

Timeline bands

People search “how long does it take to build an app” hoping for a number. The honest answer is a band that matches complexity. A focused internal tool is not a marketplace. AppsAura estimates after we map users and must-have journeys — the same rule as on our mobile app development company page.

Illustrative planning bands (not a quote): a lean first release can land in a small number of sprints after a short discovery. Feature-rich consumer or enterprise apps often take several months. Integrations, offline, payments and store review sit on the calendar whether you like it or not.

What actually takes time

  • Discovery that cuts scope — or the rewrite you pay for later.
  • UX for empty, error and permission states — not only a splash screen.
  • Backend and APIs, which is where “frontend-only” quotes go to die.
  • QA on real devices. Android diversity is not a footnote.
  • Your legal, brand and third-party KYC, which are not engineering days.

Read the mobile app development process and mobile app development cost so timeline and money describe the same product.

Store review

App Store and Play review are outside your sprint board. We prepare listings and builds; we do not control a reviewer. Buffer that in the plan.

Frequently Asked Questions

Can you ship in 20 days?
When the 20-day MVP scope fits — one journey, not a platform. See the MVP page. Most store-ready consumer apps take longer.
Does Flutter make it faster?
It removes a second native UI team. You still test two operating systems. See Flutter vs native.
