One of the first questions I get from clients: "Should we build an app?" Usually, the answer is: you need a web application, not a mobile app.
The Difference
- Mobile app: Downloaded from the App Store or Google Play. Installed on the user's phone. Requires development for both iOS and Android (unless you use a cross-platform framework).
- Web app: Accessed through a browser (Chrome, Safari, etc.). Works on any device — desktop, tablet, phone. No download or installation required.
When You Need a Mobile App
- You need offline functionality (no internet access in certain use cases)
- You need push notifications as a core feature
- You need access to device hardware (camera, GPS, accelerometer) beyond what browsers support
- You're building a consumer product where App Store presence is important for discovery
When a Web App Is Better
- Your users access the tool from both computers and phones
- It's an internal business tool (staff don't want another app on their phone)
- You need to update frequently (web app updates instantly for all users; mobile apps require users to download updates)
- Budget is limited (one web app works everywhere; a mobile app needs iOS + Android development)
The Modern Reality
Modern web apps (Progressive Web Apps / PWAs) can work offline, send notifications, and be added to the home screen — blurring the line further. For 90% of business tools, a well-built web app is the right choice.
