# Mobile App or Web App: Which Do You Need?

> Not every business needs a mobile app. A plain guide to the difference between an app and a web app, when each makes sense, and the questions to answer first.

Many business owners say "we need an app" when what they need is software that people can use on a phone. Those are not always the same thing, and choosing the wrong one can cost months. This guide explains the difference in plain terms so you can decide before you speak to a developer.

## What is the difference?

A mobile app is installed from an app store, such as Google Play or the Apple App Store, and lives on the phone like any other app. A web app runs in the browser. You open it by typing an address or tapping a link, and nothing needs to be installed. A web app can be built to fit a phone screen well, so it can feel close to an app for many tasks.

## When a web app is enough

A web app is often the better first choice, especially for business tools.

- Staff use it at a desk, on a computer or a tablet, as well as on a phone
- It is mainly forms, lists, records and reports, such as orders, customers or attendance
- You want everyone to use the same version, with no updates to install
- You want to launch sooner and spend less to start
- You are not yet sure which features people will really use

One web app also works on Android phones, iPhones and computers together, which keeps the first version simpler.

## When a mobile app makes sense

An app becomes worth the extra effort when the phone itself is part of the job.

- Work in places with poor internet, where the app must keep working and sync later
- Heavy use of the camera, location or sensors, for example delivery proof or field visits
- Notifications that need to reach people reliably, even when they are not looking at the app
- Customers who will use it every day, so having an icon on the home screen matters
- Features that depend on the phone's hardware or system settings

## The middle path

Many businesses start with a web app that works well on phones, then build a mobile app later once real use shows what people need. This is a sensible way to avoid building features nobody uses. The data and the main logic can often be reused, so the web app is not wasted work.

## Android, iPhone or both?

If you do need an app, find out which phones your own customers or staff use. Do not guess from what the market looks like in general. Supporting both is common, but starting with one can shorten the first release. There are two usual ways to build for both.

- Cross-platform, where one codebase produces both an Android app and an iPhone app. This is often faster and easier to maintain, and suits many business apps
- Native, where each platform has its own separate app. This can suit apps that need the most from the phone's hardware, but it means more work to build and keep up to date

The right choice depends on what the app must do, so ask your developer to explain why they recommend one over the other.

## The parts people forget

An app is more than the screens. Before you decide, remember that it usually needs these as well.

- A server and database behind it, so data is stored and shared safely
- Developer accounts with the app stores, and a review before the app is published
- Updates when phone systems change, so the app keeps working
- Support for users, and a plan for fixing bugs after launch

These are ongoing, not one-off, so plan for care after launch and not only the build.

## Questions to answer before you talk to a developer

- Who will use it, and on which devices?
- What is the one thing it must do well in the first version?
- Does it need to work without internet?
- Does it need the camera, location or notifications?
- Is a web app on a phone good enough to test the idea first?
- Who will look after it after launch?
