Frequently Asked Questions
- What's the difference between a mobile app and a web app?
- A mobile app is installed from an app store and runs on a phone or tablet (iOS/Android). A web app runs in a browser and is accessed by a URL. Mobile apps can more easily use device features like the camera, GPS, and offline storage, while web apps are easier to update because users don’t install new versions.
- When should I build a mobile app instead of a website?
- Build a mobile app when you need strong use of phone features (camera, GPS, Bluetooth), offline support, push notifications, or a highly optimized mobile experience (like ride-hailing, fitness tracking, banking, or messaging). If your main goal is content browsing or simple forms and you want the fastest way to reach all devices, start with a responsive website or web app.
- How much does a mobile app cost?
- Costs vary based on complexity, platforms (iOS, Android, or both), design, and backend needs. Common cost factors include development time (native vs cross-platform), ongoing maintenance, app store developer fees, cloud backend usage (compute, databases, storage, networking), third-party services (maps, payments, analytics), and operational needs like monitoring and customer support.
