How Long Does It Take to Build an App? Real Timelines, From a 2-Week MVP to a Full Product

Alexander Rocket10 min readOct 5, 2026

Agency guides say a full app takes 4 to 7 months (Uptech) and a simple MVP takes 2 to 4 months (Topflight). A narrow first release can go live in 2 weeks. We did it twice in 2026, with EasySpk and GhostMinutes.

How long each stage of an app takes

Where the months go in a typical plan

The long timelines come from stages stacked one after another. Topflight’s guide puts discovery at 2 to 4 weeks, design at 4 to 6 weeks, development for one platform at 12 to 20 weeks, testing at 3 to 5 weeks and launch at 1 to 2 weeks. Run back to back, those stages add up to 22 to 37 weeks, roughly 5 to 9 months.

A 2-week release still has discovery, design, building, testing and launch. The difference is scope. The team builds one job instead of a full product, and it reuses modules it has already built.

For the price of each stage, see how much an MVP costs, and if your app runs on AI, our guide on what an AI app costs.

What a 2-week first release looks like

Both apps started from nothing. Each founder had an idea, and everything else, down to the name, still had to be made.

EasySpk is an AI voice keyboard for iPhone: you talk, and it types clean text in any app. Two weeks after we started, it was live in the App Store with all of this made from scratch:

  • the name, the brand and the illustrations;
  • the app and landing page design;
  • the iPhone keyboard;
  • a fast, low-cost AI setup.

GhostMinutes turns meetings into a transcript with speaker names, a summary and a chat about the meeting. It also went from zero to its first iOS release in 2 weeks, and the web app followed a week later.

How the 2 weeks are planned

Our usual MVP plan gives each step a week: scope and design, the core build, finishing and testing, then the launch. A 2-week release keeps the same steps with less in each, because the first release does less.

Decisions that block other work come first, such as who the users are and the one job the app does. In an AI app, the model setup is one of them. Sign-up, payments and the admin panel come from ready-made modules, so the building time goes to the part that makes the app different.

What waited for later

A lot of work came after the first release. For EasySpk, that meant polished screens, reworked and faster flows, new features and tests of growth ideas. For GhostMinutes, it meant the web app, extra features and several ways to charge for the product. None of it had to be in the store on day one.

What takes the time you don’t plan for

Four things can hold a launch back even when the code is ready.

Store and payment accounts

To publish an app as a company, Apple asks for a D-U-N-S number to check your organization. Apple says the number can take up to 5 business days to arrive, plus up to 2 business days to reach Apple, and Apple’s own verification comes after that. A new payment account also has to be approved before you can take money.

EasySpk and GhostMinutes both launched on our Apple developer and Stripe accounts while the founders’ accounts were still waiting, so neither launch waited for approvals.

App Store review

Apple says that on average 90% of submissions are reviewed in less than 24 hours. A rejection means a fix and another round, so leave a few days in the plan for it. Keyboard apps like EasySpk also follow Apple’s separate rules for custom keyboards, which is one more thing to check before you submit.

Naming and brand

The store page can’t go up without a name and an icon, so the brand has to exist before you submit. Both founders came to us without a name. We picked the names and made the brands before the first release, inside the same 2 weeks.

Decisions nobody owns

When nobody on the founder’s side can say yes or no, work stops and waits. Our MVP cost guide lists long rounds of approvals among the things that push a price up, and they push the launch date too. Agree before you start who decides and how fast they answer.

After launch: 1-week sprints

Both apps kept changing after the first release.

EasySpk moved to 1-week sprints: polishing screens, reworking and speeding up flows, adding features and testing growth ideas. Speech processing now takes up to 1 second, down from up to 3 seconds at the start, and a plain transcription takes about half a second. The app got 1,000+ downloads in its first days.

GhostMinutes got a web app 1 week after the iOS release. It runs on the same backend, and it showed how the product does in the browser. Then came a couple of weeks of tests with the founder’s marketing team, on extra features and on how to charge. The product reached $1,500 in monthly recurring revenue (MRR).

Weekly steps keep every change small: it reaches users within days, and an idea that doesn’t work costs one week. With us, a week like that is about 80 hours of work for a small team, or roughly $3,000 to $4,500.

What makes a 2-week release possible

Our MVP development in 2 to 4 weeks is built on six things:

  • A narrow first release: one type of user, one main job, and only the features needed to test the idea.
  • Ready-made modules: sign-up, payments and the admin panel are already built, so we don’t start from zero.
  • AI tools in development: our developers use AI tools in their work, and our AI R&D department builds AI-native ways of working.
  • A small senior team, with fewer people and fewer hand-offs between them.
  • Startup methods: Extreme Programming, Scrum, Customer Development and Lean Startup.
  • Our own store and payment accounts, for founders whose accounts are still waiting for approval. EasySpk and GhostMinutes both launched this way.

If you don’t yet know what the one job of your app is, start with a discovery sprint. For the wider case for launching early, read our guide to reducing time to market.

When 2 weeks is not realistic

Some products shouldn’t be squeezed into 2 weeks, and it’s better to know that before you start. Plan for longer if your app:

  • holds client money, lends money or has to follow other financial rules;
  • stores health data or other personal data that the law protects;
  • is a marketplace where buyers and sellers each need their own screens and payouts;
  • depends on old or badly documented systems;
  • works with hardware.

Each of these adds time in a way you can estimate. Topflight counts about 1 to 2 weeks for every outside service the app connects to, and 1.3 to 1.6 times the effort for a second platform built from scratch. That is one more reason to start on one platform, as GhostMinutes did with iOS.

Guides put a mid-size app with payments and admin tools at 4 to 8 months, and enterprise platforms at 9 to 18 months or more (Appinventiv). In these cases we start with something small that answers the hardest question first. For an AI product, that is a pilot: $5,000 to $15,000 and 2 to 4 weeks with us.

Technical co-founder, fractional CTO or agency: which is fastest?

Who builds your app also decides when the work can start.

Technical co-founderOnce you find the right personDepends on their time and skillsYes, a share of the companyUsually equity instead of a full salary
Full-time CTOHiring takes 3-6 months, by JetRockets’ estimateAfter the hire, they still need a team to buildYour choice$250,000-400,000+ a year, by JetRockets’ estimate

Agency (Rocketech)Once the scope is agreed2-4 weeks for an MVPNo$5,000-15,000 for an MVP
Who gets you to a first release fastest

The JetRockets figures come from its fractional CTO page.

On EasySpk and GhostMinutes we worked as a fractional tech co-founder. We led the technical side, built the product and launched it on our accounts, and each first release took 2 weeks. The cash part was $12,000 for EasySpk and $15,000 for GhostMinutes, inside our fixed MVP price of $5,000 to $15,000. In a co-founder deal, part of our fee can be a small equity stake, which gets diluted like everyone else’s when the startup raises money.

Our fractional CTO page has the packages, and engagement models compares all five ways to work with us, from a fixed-price MVP to a co-founder partnership.

Questions about app timelines

How long does it take to build an app?

Agency guides put a full app at 4 to 7 months. With us, a narrow first release takes 2 to 4 weeks, and the rest of the product grows from it in 1-week sprints.

How long does it take to build an MVP?

Usually 2 to 4 weeks with us, and a smaller MVP can fit into 2. Agency guides put a simple MVP at 2 to 4 months. The difference comes from keeping the first release to one job and using modules we’ve already built.

Can you really launch an app in 2 weeks?

Yes, if the first release does one job. EasySpk and GhostMinutes each reached the App Store 2 weeks after we started. Apps that hold client money, store health data or connect two sides of a marketplace need longer.

How long does App Store review take?

Apple says that on average 90% of submissions are reviewed in less than 24 hours. If the app is rejected, you fix it and submit again, so keep a few days of room in your plan.

How can I launch before my Apple developer account is approved?

Launch on a partner’s accounts. EasySpk and GhostMinutes both went live on our Apple developer and Stripe accounts, so the founders didn’t have to wait for their own accounts to be approved.

What slows app projects down the most?

A first release that keeps growing, decisions that wait for days, and new store and payment accounts that wait for approval. Each of these can keep a finished app out of the store.
