Web App vs Mobile App: Which Does Your Business Actually Need?
Most businesses that ask for "an app" don't need one from the App Store. Here's the difference between a web app and a mobile app — and how to choose.

"I need an app" usually means one of two things
When a business says "we need an app", they almost always mean one of two very different things — and the difference is thousands of pounds and months of work. So before anyone quotes you, it's worth getting the terms straight.
A mobile app is the thing you download from the App Store or Google Play — it lives on your phone's home screen. A web app is software you use in a browser, like a login area, a dashboard, a booking system or a customer portal — no download, no app store, just a web address. Both can feel app-like. They cost and behave very differently. Here's how to tell which one you actually need.
What a web app is (and why it's usually the answer)
A web app is a proper piece of software that runs in the browser — think of your online banking, a booking system, or a members' area, rather than a brochure website.
- How people use it: they go to a URL and log in. Works on any device with a browser — phone, tablet, laptop — with no download.
- What it's great for: dashboards, portals, booking and scheduling, internal tools, anything with logins and data. Most business software is a web app.
- Cost and time: you build it once and it works everywhere, so it's usually far cheaper and faster than building for each phone platform separately. (We break the numbers down in how much a custom web app costs.)
- Updates: you push a change and everyone has it instantly — no app-store review, no waiting for users to update.
For the large majority of businesses that come to us saying "we need an app", a web app is what they actually need — the software solves the problem, and forcing it into an app store adds cost and friction for no real gain.
What a mobile app is (and when it's genuinely worth it)
A native mobile app is built specifically for iOS and/or Android and installed from the app store.
- How people use it: they download it and it lives on the home screen, with a native feel.
- What it's great for: things that genuinely need the phone's hardware or behaviour — push notifications as a core feature, camera or sensor access, offline use, or a consumer product people open every day.
- Cost and time: typically higher, because iOS and Android are effectively two builds, plus app-store approval and ongoing maintenance for each.
- The honest test: a native app is worth it when the phone itself is central to the experience, or when you truly need a home-screen presence people return to daily. If it's really "our web app, but as an icon", there are lighter ways to get there.
The bit in the middle — a web app that feels like an app
You don't have to choose as starkly as it sounds. A modern web app can be built as a progressive web app (PWA) — installable to the home screen, working offline, sending notifications — without the cost of two native builds or the app-store gatekeeping. For a lot of businesses this is the sweet spot: the reach and economics of the web, most of the feel of an app.
It's why we usually start from the web. You get software that works everywhere on day one, and you can add native builds later if real demand proves you need them — rather than paying for two app stores up front on a hunch.
How to decide
Run your idea through three questions:
- Does it need the phone's hardware or offline use as a core feature (camera, sensors, always-on notifications, works-on-the-tube)? If yes, lean native. If not, a web app almost certainly covers it.
- Who uses it, and how often? A daily consumer habit justifies a home-screen icon. A tool your customers or staff use now and then works better as a web app they just log into.
- What's the budget and timeline? One web build that works everywhere is faster and cheaper than two native builds. If you need to be live and useful soon, the web is usually the route.
If the honest answer is "we've outgrown spreadsheets and need real software", the format matters less than getting the software right — the signs you've outgrown spreadsheets and custom software vs off-the-shelf are the next reads.
How we build
We build web apps, portals and custom platforms — software shaped around how a business actually works, not squeezed into an off-the-shelf tool. That's the custom platforms and portals we build and the custom software side of the studio, including for businesses across Cheshire. If you're weighing a native app specifically, we'll tell you honestly whether you need one — most of the time, a well-built web app does the job for less.
Frequently asked questions
- What's the difference between a web app and a mobile app?
A mobile app is downloaded from the App Store or Google Play and lives on your phone. A web app runs in a browser at a web address — a login area, dashboard, booking system or portal — with no download. Both can feel app-like, but a web app works on any device from one build, while a mobile app is built specifically for iOS and Android.
- Do I need a mobile app or a web app for my business?
Most business software — portals, dashboards, booking systems, internal tools — is best built as a web app: one build that works everywhere, cheaper and faster to make and update. A native mobile app is worth it when the phone's hardware or offline use is central, or when you genuinely need a home-screen presence people open daily.
- Is a web app cheaper than a mobile app?
Usually, yes. A web app is built once and works on every device with a browser. A native mobile app effectively means two builds — iOS and Android — plus app-store approval and separate ongoing maintenance. If budget and time matter, the web is normally the more cost-effective route.
- Can a web app work like a mobile app?
Yes. A progressive web app (PWA) can be installed to the home screen, work offline and send notifications — much of the feel of a native app without the cost of two builds or app-store gatekeeping. For many businesses it's the sweet spot between reach and app-like experience.
- I asked a developer for "an app" — what do I actually need?
Get the terms straight first, because it changes the cost significantly. If you're describing software with logins and data — a portal, booking system or dashboard — you almost certainly want a web app. If the phone itself is central to the experience, you may want native. A good studio will ask what the software has to do before quoting you an app-store build.
