Web app vs mobile app: which does your business need?
· 6 min read
"We need an app" almost always arrives already decided, and often it is decided wrongly — not because mobile apps are bad, but because the phrase covers three quite different things with very different costs.
The three options
| Option | What it is | Typical fit |
|---|---|---|
| Web app | Runs in the browser, works on phones and desktops, nothing to install | Internal systems, dashboards, anything used at a desk or occasionally on a phone |
| Native mobile app | Installed from the App Store or Play Store, written for the platform | Daily use on a phone, offline working, camera, GPS, push notifications |
| Cross-platform app | One codebase producing both iOS and Android apps | Most mobile apps that are not graphically demanding |
Why a web app is usually the right start
It works everywhere immediately, needs no app store approval, and updates the moment you deploy — nobody is running last month's version because they never tapped update. It is also the cheapest of the three to build and to keep running, which matters more than it sounds: you will be maintaining this for years.
Modern web apps can be installed to a phone's home screen, work offline to a degree, and send notifications on most platforms. The gap with native is narrower than it was.
When you genuinely need native
- The app is used in the field, often without a reliable connection.
- It depends on the camera, GPS, Bluetooth or sensors in a sustained way — scanning all day, not uploading a photo occasionally.
- Push notifications are core to the product rather than a convenience.
- People use it several times a day and an app icon genuinely changes whether they open it.
- You are selling to consumers who expect to find you in an app store.
The cost difference is ongoing, not one-off
A native app is not just more expensive to build. It has to be maintained against two operating systems that release annually, it needs developer accounts, and every change waits for review. A web app has none of that. Over three years the difference is usually larger than the original build cost.
A practical way to decide
Ask where the person is standing when they use it. At a desk, or moving between one, points firmly at a web app. On a forklift, a building site, in a van or walking a warehouse points at mobile. If the honest answer is "mostly at a desk, but it would be nice on a phone", build the web app and make it work properly on a phone.
Building both at once is the most expensive option and rarely the right first move. Build the one that matches the primary use, and add the other when there is evidence it is needed.
If the answer is the browser, web application development covers what that involves. If it is genuinely a phone in someone's hand all day, mobile is the other half of the same conversation.
For the cases where it really is native — field work, offline, sensors — our mobile app development work sets out how we approach iOS and Android without building the same thing twice.
