What decides how much a mobile app costs?
Like any custom software, an app costs the effort to build it multiplied by the rate of the team. The effort depends far less on the number of screens than on what happens behind them: who the users are, what data the app stores, which systems it talks to and how reliable it has to be.
Two apps that look similar in a design file can differ greatly in cost. A catalogue app that shows products is much simpler than one that takes payments, tracks deliveries in real time and works offline.
Native or cross-platform: which costs less?
Native apps are built separately for iOS in Swift and for Android in Kotlin. They give the most direct access to device features and platform-specific behaviour, but you maintain two codebases.
Cross-platform frameworks such as Flutter and React Native share most of the code between iOS and Android, which usually lowers both build and maintenance cost. They are a good fit for most business, commerce and service apps. Native development still makes sense for apps that depend heavily on advanced device features, demanding graphics or the newest platform capabilities on release day.
Which features add the most cost?
These features commonly change an estimate the most:
- User accounts with social login, one-time passwords and role-based permissions
- Payments, subscriptions, wallets and refunds, including payment gateways such as Razorpay or Stripe
- Real-time features: live tracking, chat and instant notifications
- Maps, background location, camera, Bluetooth or other device hardware
- Offline mode and syncing data when the connection returns
- Multiple apps for different roles, such as customer, delivery partner and vendor apps
- An admin panel to manage users, content, orders and reports
- Integrations with ERPs, CRMs, logistics or accounting systems
What goes into an app besides the app itself?
A typical app project includes product discovery and UX design, the mobile app or apps, a backend with APIs and a database, an admin web panel, cloud infrastructure, analytics and crash reporting, testing on real devices, and the work of publishing to the App Store and Google Play. When comparing quotes, check that each one covers all of these — a low quote often leaves out the backend or the admin panel.
How long does it take to build an app?
A focused first release usually takes 8–16 weeks, including design, development, testing and store submission. Apps with several user roles, complex payments or many integrations take longer and are best delivered in phases. Store review adds a short wait before launch, and Apple's review in particular can request changes, so leave time for it in your plan.
What does an app cost after launch?
Budget each year for cloud hosting, third-party services such as maps, messaging and notifications, developer account fees, monitoring and bug fixes, and updates when new iOS and Android versions are released. Most successful apps also keep adding features based on user feedback, so plan a roadmap budget, not just a maintenance budget.
How can you reduce the cost of your app?
Without cutting quality, the most effective ways are:
- Define the one job the first release must do well, and leave everything else for later releases
- Use a cross-platform framework unless you have a specific reason to go native
- Use proven services for login, payments, notifications and maps instead of building them
- Validate the design with a clickable prototype before development starts
- Start with a short discovery sprint so the estimate is based on a clear scope
