The three options
A web app runs in a browser on any device. There is nothing to install: people visit a link and sign in. Customer portals, booking systems, dashboards and most internal business tools are web apps.
A native mobile app is installed from the Apple App Store or Google Play. It has full access to the phone's features and can work without a connection, but it must be built for each platform and approved by each store.
A progressive web app (PWA) is a web app that can be added to the home screen and behaves more like an installed app, with some offline support and, on many devices, notifications. It is a useful middle ground, though support for some features still varies between Android and iOS.
Side-by-side comparison
| Factor | Web app | Native mobile app |
|---|---|---|
| Reach | Any device with a browser, from one link | Users must find and install it from a store |
| Discovery | Found through Google and other search engines | Found through app store search and your own promotion |
| Device features | Limited access to camera, location and sensors; notification support varies | Full access to camera, location, biometrics, notifications and background tasks |
| Offline use | Possible but limited | Strong offline support |
| Updates | Instant for everyone when you deploy | Go through store review; users may delay updating |
| Build cost | One codebase for all devices | More design, testing and release work per platform |
| Ongoing work | Browser and security updates | Yearly iOS and Android releases, store policies and developer accounts |
| Store fees | None | Developer account fees and, for some digital sales, store commissions |
When a web app is the right choice
- Usage is occasional. Few people install an app they will open a few times a year. For booking an appointment, checking an order or paying an invoice, a link is easier.
- New customers find you through search. Web pages can be indexed by search engines; screens inside a mobile app cannot.
- Work happens at a desk. Dashboards, reporting, data entry and administration are easier on a large screen with a keyboard.
- You need to launch quickly or test an idea. One codebase and no store approval means a faster, cheaper first release.
- You change things often. Updates reach everyone immediately.
When a mobile app is the right choice
- People use it frequently. Daily or weekly use justifies a home-screen icon and a fast, native experience.
- Notifications matter. Reminders, status updates and alerts are most reliable in native apps.
- You need device features. Scanning barcodes, taking photos for a job record, capturing signatures, tracking location or using Face ID all work best natively.
- Connectivity is unreliable. Field staff in basements, rural areas or job sites need apps that keep working offline and sync later.
- Your customers expect it. In some markets, such as loyalty programs or member services, an app is part of the expected experience.
Cost and maintenance differences
A web app usually costs less to build and maintain because there is one codebase and no store process. Native apps add design work for each platform's conventions, testing on a range of real devices, store listings, privacy disclosures and review, and a yearly cycle of updates when Apple and Google release new operating system versions. Cross-platform frameworks can reduce the cost of supporting both iOS and Android, but they do not remove store work or device testing.

A common path: web first, mobile next
Many successful products start as a mobile-friendly web app. It reaches everyone quickly and shows which features people use. If usage is frequent and phone features would add real value, native apps follow, built on the same backend and data. Because the core logic already exists, the mobile apps focus on the experience rather than rebuilding the business rules.
The reverse also happens: for a field-service crew or a product that depends on notifications, the mobile app is the main product and a web dashboard is added for office staff and administrators.
Questions to help you decide
- How often will a typical user open it: daily, weekly, monthly or rarely?
- Will new users find it through search, or will you invite them directly?
- Does it need the camera, location, notifications or offline access to be useful?
- Will people mostly use it on a phone, a computer or both?
- How quickly do you need a first version, and what is the budget for the first year?
If most answers point to occasional use, search discovery and desk-based work, start with a web app. If they point to frequent use, phone features and work on the move, a mobile app is likely worth it.
Frequently asked questions
Can one app work on the web, iOS and Android?
Partly. Cross-platform frameworks can share much of the code between platforms, and a shared backend means all versions use the same data. Each platform still needs its own testing and release work.
Do I need a website if I have an app?
Yes. A website is how people and search engines find and verify your business, and the app stores require links to a support page and privacy policy.
Is a progressive web app enough?
For many business tools, yes. If you need reliable background notifications on every device, deep hardware access or an app store presence, choose native.
