How Long Does It Take to Build an App? A Realistic Timeline
Weeks or months? It depends on what the app does, but the stages are always the same. Here is a realistic timeline, and the store rules and delays that catch most first-time app owners out.
A simple app (an MVP with a handful of core features) usually takes around 6 to 10 weeks to build and launch. A full-featured app with payments, an admin panel and several user types usually takes 3 to 6 months, delivered in stages. Very large platforms take longer. The biggest factors are the number of features, the backend, and how quickly decisions and content come from your side.
Typical app timelines by type
| Type of app | Example | Typical time to launch |
|---|---|---|
| Simple MVP | Booking or enquiry app, catalogue, loyalty app | 6–10 weeks |
| Business app with backend | Field staff app, attendance, order taking | 2–4 months |
| E-commerce / ordering app | Store app with cart, UPI and cards, order tracking | 3–5 months |
| On-demand / marketplace | Delivery or service booking with customer, partner and admin apps | 4–8 months, in phases |
These are ranges, not promises. A good agency gives you a timeline for your specific feature list, broken into milestones you can check.
The stages of building an app
1. Discovery and scoping (1–2 weeks)
You and the team agree on who the app is for, the features in version one, and what can wait. The output is a feature list, user flows and a fixed plan. Skipping this step is the single most common reason apps run late.
2. UI/UX design (2–3 weeks)
Designers create every screen and a clickable prototype you can try on your phone. Changes here take hours; the same changes after development can take weeks.
3. Development (4 weeks to several months)
The app, the backend (server and database) and usually an admin panel are built in short cycles called sprints. You should receive test builds on your own phone every week or two.
4. Testing (1–3 weeks, overlapping development)
The app is tested on budget and flagship phones, Android and iPhone, and on slow networks. Payment flows, logins and notifications get special attention.
5. Store submission and launch (a few days to 3+ weeks)
Store listings, screenshots, privacy details and review notes are prepared and the app is submitted. How long this takes depends on the store rules below.
Play Store and App Store approval: what to expect
Many first-time app owners are surprised by the store steps. Plan for them from the start:
- Apple App Store: Apple says most submissions are reviewed within 24 hours, but a rejection means fixing and resubmitting. You need an Apple Developer Program membership, which is a yearly fee.
- Google Play: reviews can take from a few hours to several days, and longer for new developer accounts. There is a one-time registration fee.
- Google Play testing rule: new personal developer accounts must run a closed test with at least 12 testers for 14 days in a row before they can publish to everyone. Organisation accounts are not subject to this rule but need business verification, such as a D-U-N-S number.
- Both stores ask for a privacy policy, and details of what data your app collects.
A real example from our own work: Apple once rejected an app because the demo login we had given its reviewers had been deleted by an automatic clean-up job on the server. The fix took minutes, but the resubmission cost days. Now we protect reviewer accounts on every project.
What slows app projects down
- Features added halfway through. Keep a “version two” list instead.
- Slow feedback. A week of waiting for approval on designs is a week added to launch.
- Missing content: logos, product photos, prices and text arrive late.
- Third-party delays: payment gateway approval, SMS sender ID and WhatsApp template approval, or access to your existing software.
- Store accounts opened at the last minute, especially organisation accounts that need verification.
How to launch faster
- Start with an MVP: the smallest version that solves the main problem well.
- Use cross-platform development (Flutter or React Native) to build Android and iPhone together. See Flutter vs React Native.
- Create your Play Console and Apple Developer accounts in week one.
- Name one person on your side who can approve decisions quickly.
- Agree milestones with working builds, so you see progress instead of waiting for a big reveal.
The bottom line
Most business apps take between two and six months, and a focused MVP can launch in under three. Good scoping, quick decisions and early store setup make more difference than anything else. For costs, read app development cost in India, or see how we work on our mobile app development page.
Frequently asked questions
How long does it take to build a simple app?
A simple MVP with a few core features usually takes about 6 to 10 weeks, including design, development, testing and store submission.
How long does App Store approval take?
Apple says most submissions are reviewed within 24 hours. If the app is rejected, you fix the issue and resubmit, which adds time.
How long does Google Play approval take?
Reviews take from a few hours to several days. New personal developer accounts must first run a closed test with at least 12 testers for 14 days before publishing to everyone.
Can an app be built in one month?
A very small app with one or two features can be, but most business apps need longer to be designed, tested and approved properly. Rushing usually means more bugs after launch.
Does building for both Android and iPhone double the time?
Not with cross-platform tools like Flutter or React Native, which build both from one codebase. Separate native apps take considerably longer.
