“How much does an app cost?” has no single answer, for the same reason “how much does a building cost?” doesn’t. What you can know is which decisions drive the cost, so you can plan a budget, compare quotes properly, and spend where it matters.
1. Platforms
An app for iOS only, Android only, or both. Building both natively means two codebases. Cross-platform frameworks such as Flutter and React Native let one codebase serve both, which usually lowers cost. Native development remains the right call for apps that rely heavily on device hardware or platform-specific capabilities. A web app or progressive web app may be enough for some internal tools.
2. Features and complexity
Cost follows the number and difficulty of features, not the number of screens. Simple features include content, forms and profiles. Features that add significant effort include:
- payments and subscriptions;
- real-time chat, tracking or live updates;
- offline mode with synchronisation;
- maps, location and geofencing;
- video and audio;
- AI features such as recommendations, assistants or image recognition.
3. Backend and admin tools
Most apps need a server side: an API, a database, authentication, notifications, file storage, and an admin panel for your team to manage users, content and orders. This is often a large share of the work and is easy to leave out of early estimates.
4. Integrations
Connecting to payment gateways, CRMs, ERPs, logistics providers, SMS and email services or your existing systems adds work, especially when their APIs are limited or poorly documented. List every integration up front.
5. Design
A polished, accessible experience requires user research, flows, interface design and prototypes tested with real users. Good design costs money upfront and saves far more by avoiding rework and features nobody uses.
6. Security and compliance
Apps handling payments, health, financial or other personal data need stronger authentication, encryption, secure storage, audit trails and compliance with the rules in your sector and markets. Requirements here can shape the architecture, so identify them early.
7. Testing
Apps must work across many devices, screen sizes and operating system versions. Budget for automated tests, manual testing on real devices, and beta testing with real users before release.
8. Release
Publishing involves developer accounts, store listings, screenshots, privacy disclosures and review by Apple and Google, which can take several rounds. Plan time for it.
9. Team and engagement model
Rates differ by location, seniority and engagement model: fixed price, time and materials, or a dedicated team. Compare the experience and completeness of the team, not just the hourly rate. A cheaper quote that omits testing, design or an admin panel is not cheaper. Our checklist for choosing a software development company covers what to compare.
10. Maintenance after launch
Apple and Google release major operating system updates every year, and apps need updates to stay compatible. Add hosting, monitoring, security patches, bug fixes and improvements based on user feedback. Treat these as a recurring budget line.
How to control the cost
- Start with a focused first release (MVP): the smallest set of features that proves value to real users.
- Prototype before building: a clickable prototype tested with users catches expensive mistakes cheaply.
- Use cross-platform where it fits.
- Use proven services for authentication, payments, notifications and maps instead of building your own.
- Write the scope down, including the backend, admin panel, integrations and non-functional needs such as security and performance.
- Phase the roadmap, funding later features from what you learn after launch.
How to get an estimate you can trust
A reliable estimate comes after a short discovery phase that produces user flows, a feature list with priorities, integration details and technical decisions. Ask each company to quote against the same written scope, and to state clearly what is included, from design and testing to deployment and support. That turns “how much does an app cost?” into a number you can plan around.
