A mobile app is a client for a system: the screens on the phone, and the backend, admin tools and integrations behind them. Budgets that count only screens are usually short by the largest part of the work.
Native or cross-platform
Separate native apps (Swift for iOS, Kotlin for Android) give the most direct access to each platform and cost roughly two codebases. A cross-platform framework such as React Native or Flutter shares most code across both and suits most business apps. Native is worth it when the app depends heavily on platform features, demanding graphics or the newest operating-system capabilities on release day.
Where the build effort goes
- Backend and APIs: accounts, data, business rules and the admin panel your team uses.
- Screens and flows: design and build of each journey, on many screen sizes.
- Integrations: payments, maps, messaging, analytics and any existing system you run.
- Offline behaviour: storing data on the phone and syncing it safely when the connection returns.
- Real-time features: chat, live tracking and notifications.
- Device features: camera, location, biometrics, Bluetooth or external hardware.
- Testing on real devices and preparing store listings and review submissions.
Costs beyond the build
- Store accounts: Apple charges an annual developer membership; Google Play charges a one-time registration fee.
- Hosting, push notifications and third-party service fees, which grow with users.
- Updates when Apple and Google release new operating-system versions or change store rules.
- Monitoring crashes and fixing them, and supporting older devices your users still have.
How to keep the cost down
- Ask whether a responsive web app would do; it avoids store reviews and two platforms.
- Choose cross-platform unless a specific feature needs native code.
- Reuse one backend for the app, the website and the admin panel.
- Release a first version with the core flow and add features from real usage.
How to get a number you can trust
List the user types, the core flows, the integrations and whether the app must work offline. A discovery phase turns that into screens, an architecture and a fixed quote. A price given from a feature list alone is a guess about the backend.
Questions people ask
Is Flutter or React Native cheaper than native?
- For most business apps, yes, because one codebase serves iOS and Android. The saving shrinks if the app needs a lot of platform-specific code.
Do we need a backend for our app?
- Almost every app with accounts, shared data or payments does. Managed services can reduce how much has to be built, and the discovery phase decides what to build and what to buy.
How much does it cost to maintain an app?
- Plan a yearly maintenance budget for operating-system updates, store rule changes, security fixes and small improvements. The amount depends on how many integrations and devices the app supports.
How does Vayro price mobile apps?
- As a fixed-scope build after discovery, or a monthly team for longer roadmaps. Starting prices are on our pricing page.
