"How much does it cost to build an app?" is the first question almost every client asks, and the honest answer is always: it depends on the scope. A simple catalog app and an ordering app with payments, maps, and real-time notifications are two very different jobs. This article helps you understand the cost components and work stages so you can set a realistic budget.
App development stages
1. Discovery and requirements analysis
The development team and you agree on business goals, primary users, and features. The result is a prioritized feature list that separates the MVP (the minimum viable version worth releasing) from later-phase features.
2. UI/UX design
Wireframes and interactive prototypes are built in Figma. Skipping this stage is expensive: changing a design in a prototype is far cheaper than changing finished code.
3. Development
Development runs in 1–2 week sprints with a demo at the end of each sprint. A mobile app has two parts: the app on the phone and the backend/API (authentication, database, business logic, admin dashboard). We use React Native for a single Android and iOS codebase, with a Laravel and MySQL backend.
4. Testing
Functional testing, device testing (various brands and screen sizes), API load testing, and UAT by your team.
5. Publishing
Preparing developer accounts, icons, screenshots, descriptions, and a privacy policy, then going through the Google Play review (usually a few days) and App Store review (1–3 days, though rejections over guideline issues are fairly common).
6. Maintenance
Phone operating systems are updated every year; apps need adjustments, bug fixes, and regular security updates.
Factors that determine cost
| Factor | Impact |
|---|---|
| Number and complexity of features | Largest; every feature = working hours |
| Platform | One codebase (React Native) is cheaper than two separate native apps |
| Design | Fully custom costs more than standard components |
| Integrations | Payment gateways, maps, WhatsApp, third-party APIs |
| Backend & admin | The admin dashboard is often as big as the app itself |
| Security & scale | Thousands of users vs. hundreds of thousands changes the architecture |
As a rough guide, a mobile app with an API backend and store publishing at mid-sized business scale is usually delivered in 8–16 weeks. Our Mobile App package starts at the price listed in the catalog and is finalized after a requirements analysis.
Common mistakes
- Building every feature at once. Release an MVP first and learn from real users.
- Ignoring the backend and admin dashboard. Without an admin, every content change has to go through a developer.
- Not setting up developer accounts in the company's name. The accounts must belong to your business, not the vendor.
- Not budgeting for maintenance. Set aside 15–20% of the development cost per year.
Tips to save without sacrificing quality
- Use standard UI components for secondary screens, and go custom only on the main flows.
- Start with one platform if most of your users are on Android, then follow with iOS.
- Ask for per-feature estimates so priorities are easy to trade off.
