A stage-by-stage look at mobile app timelines, from discovery to app store, plus the factors that stretch or shorten a build.
By GGP Editorial
If you're planning an app and asking how long it takes, the honest answer is three to six months for a typical product, and longer for anything complex. Simple apps can ship in two to three months. Large apps with real backend work, payments, or hardware integration run seven to twelve months, sometimes more. The range is wide because the scope, not the calendar, decides the date.
Most delays on an app project don't come from slow developers. They come from features that keep changing after the build starts. The timeline below assumes you lock the scope first. If you don't, add weeks.
| App type | What it is | Typical timeline |
|---|---|---|
| Simple app | A few screens, basic backend, no payments or heavy integrations | 2–3 months |
| Standard app | Login, profile, payments, backend, push notifications, admin panel | 3–6 months |
| Complex app | Real-time features, chat, video, maps, hardware, or multi-role logic | 7–12+ months |
Most business apps sit in the middle band. A customer-facing app with accounts, a payment flow, and an admin dashboard is a three-to-six-month job for a full team — not a weekend project. Our mobile app development cost guide walks through what that same project costs, since time and budget move together.
An app build breaks into clear phases. Here's how a standard three-to-six-month project typically distributes the time.
| Phase | What happens | Typical time |
|---|---|---|
| Discovery and scope | Requirements, feature list, and the "what we won't build" list | 1–2 weeks |
| UX and design | Wireframes, user flows, high-fidelity screens | 2–6 weeks |
| Development | Backend, APIs, frontend, and app screens, built in sprints | 6–16 weeks |
| QA and fixes | Testing, bug fixes, device compatibility passes | 2–4 weeks |
| Launch and review | App store submission, review, and release | 1–3 weeks |
Design and development overlap in practice. You don't wait for every screen to be finished before a single line of code gets written. A competent team starts the backend while design finishes the later screens, which is one reason the total is shorter than the sum of the parts.
App store review is the phase people forget to plan for. Apple's review can take a day or a week, and Google Play is usually faster, but neither is instant. Budget a week of buffer for submission and fixes.
Take a standard customer app: sign-up and login, a product catalog, a cart and checkout, order history, and a simple admin panel for the business owner. Here's how the weeks usually land.
The discovery phase takes about a week — long enough to write down the features and the things explicitly out of scope. Design runs two to three weeks, and development overlaps it. The backend (accounts, catalog, orders, and a payment integration) takes a developer a few weeks, while the app screens build up in parallel. Total time to a launchable product: roughly four to five months with a team of three or four people, including QA and app store review.
Cut the admin panel or the cart to the simplest version, and that same app can ship in three months. Add a real-time chat feature or a loyalty program, and it drifts toward six. The scope is the schedule.
A few specific things move the date more than anything else.
The app screens are rarely the hard part. Connecting to payment providers, third-party APIs, or a system you already run is where projects lose weeks. A payment gateway integration with subscriptions is a project on its own — we've written a full guide on it because it keeps surprising people.
Building for iOS only is faster than both platforms. Building native for both roughly doubles the client-side work unless you use a cross-platform framework.
Every "nice to have" screen costs time. The gap between a five-screen MVP and a twenty-screen product is often months, not weeks.
Custom, brand-specific UI takes longer than adapting a component library. It's worth it for a consumer product; less so for an internal tool.
If the app touches payments, health data, or personal information, expect extra time for security review and compliance before launch. These checks are not optional, and they are not something you can schedule around by cutting corners — build them into the plan from the first week.
If you need both iOS and Android, a cross-platform framework like Flutter or React Native usually ships faster than two native builds, because you write most of the code once. The trade-off is that very specialized features — heavy graphics, deep hardware access, or unusual native capabilities — can push you back toward native. For most business apps, cross-platform is the faster route, and it's the one we recommend when the app is straightforward.
The same rules apply to internal apps, but the timeline usually drops. A field-service app for your own staff doesn't need the polish of a consumer product, and it often ships on one platform with a smaller design budget. An internal app that would take four months as a customer-facing product can ship in two to three, because the design bar is lower and you can cut the parts users won't see. If the app is for your own team, say so up front — it changes both the timeline and the cost.
The fastest way to shorten a launch is to launch less. An MVP with three to five core screens can ship in six to ten weeks, while the full vision takes months. That's the whole point: get the core flow into users' hands, learn what they actually use, then build the rest. We've written about MVP development in depth, but the timeline version is simple — every feature you cut before the first build is time you get back.
This is how we approached Africa Life, a lifestyle app that launched on the App Store. It started as a focused set of core services and grew from there. You can read more in the case study if you want to see what a shipping mobile app actually looks like.
Only up to a point. Adding engineers to a two-person team can genuinely speed things up. Adding a seventh person to a well-running six-person team often slows it down, because communication and review overhead grow faster than the output. For most app builds, three to five people is the sweet spot. More than that and you're usually paying for coordination, not code.
Lock the scope before development starts. A one-week discovery phase that produces a written feature list saves more time than any optimization later.
Build the backend first. Most app projects stall on integrations, not screens. Starting the backend early surfaces the hard problems while there's still time to solve them.
Use a cross-platform framework if you need both stores. It's the single biggest timeline reduction available for a standard app.
Assign one decision-maker. Projects slow down when every screen needs three approvals. A single product owner with authority to say yes keeps sprints moving.
Plan the store review in from day one. Build the buffer into the schedule instead of discovering it at the end.
How long does a mobile app MVP take?
A focused MVP with three to five core screens usually takes six to ten weeks. It goes faster when you're willing to cut features for the first version.
Is iOS or Android faster to build?
Neither is dramatically faster in isolation. Building both natively is roughly double the client work, which is why cross-platform frameworks are popular.
Can an app launch in under two months?
A very simple app with a small scope can, if the requirements are locked and the team is dedicated. Anything with accounts, payments, or a backend will push past that.
Why do app projects run late?
Changing requirements mid-build is the top cause, followed by underestimated integration work and late feedback cycles. The technical work itself is usually the most predictable part.
Do I need to plan for app store review time?
Yes. Budget a week or so for Apple and Google review, including time for any fixes they request.
What's the fastest app you can realistically ship?
A single-platform app with a small feature set and a locked scope can ship in about two months. The more you add after that — a second platform, payments, an admin panel — the closer you get to the three-to-six-month range.
