What is a progressive web app?

A PWA is a website built to behave like an app. Users can install it to their home screen, it can work offline, send notifications and load fast — without downloading anything from an app store. It's accessed through a normal web address.

Are PWAs cheaper than native apps?

Usually yes. A PWA is one codebase serving all devices, so you avoid building and maintaining separate iOS and Android apps. For many businesses that's a significant saving in both build and upkeep.

Do PWAs work on iPhones?

Yes, though Apple supports some PWA features more fully than others. Core functions like home-screen installation and offline use work, but certain advanced capabilities are more limited on iOS than on Android.

When should I choose a native app over a PWA?

Choose native when you need deep device features, maximum performance, app store presence for discovery, or capabilities iOS restricts for PWAs. For content, services and ecommerce, a PWA often does the job for far less.

Progressive Web Apps (PWAs): Are They Worth It?

Every few years a technology arrives promising to make expensive native apps obsolete, and progressive web apps are the current contender. The pitch is seductive: get most of what an app does, for a fraction of the cost, without the app stores. For some businesses that's genuinely true. For others it's a way to end up with something that pleases no one.

Because building an app is one of the larger investments a business can make, it's worth understanding what PWAs really are, where they genuinely shine, and where the marketing oversells them. Here's the clear-eyed version.

What a PWA actually is

A progressive web app is a website engineered to behave like an app. Visitors reach it through a normal web address, but it can be 'installed' to the home screen, launch in its own window without browser clutter, work offline or on patchy connections, load quickly, and send push notifications — the things that used to require a downloaded app.

The key difference from a native app is delivery. A native app is built specifically for iOS or Android and downloaded from an app store. A PWA is one website that works everywhere, with no store, no download, and no separate versions to maintain.

Key takeaway: A PWA gives you app-like features from a single website at a fraction of native-app cost. It's an excellent fit for content, services and many ecommerce sites — but native still wins when you need deep device features, peak performance or app store discovery.

The genuine advantages

One codebase, every device. No separate iOS and Android builds to develop and maintain — a major saving in time and money.
No app store friction. Users don't have to find, download and install from a store. They just visit your site and add it to their home screen.
Always up to date. Because it's a website, everyone gets the latest version instantly — no waiting for users to update an app.
Discoverable. A PWA appears in Google search like any website, so your SEO still drives traffic to it.
Cheaper to build and run. One project, one team, lower ongoing maintenance.

The honest limitations

PWAs aren't magic, and any provider who pretends otherwise isn't being straight with you.

Consideration	PWA	Native app
Build cost	Lower	Higher
Deep device features	Limited	Full access
iOS feature support	Partial	Full
App store presence	None by default	Yes (discovery channel)
Peak performance	Very good	Best

The main caveats: Apple supports some PWA features less fully than Android, so certain capabilities are restricted on iPhones. PWAs also can't reach the deepest device hardware and performance that demanding apps — graphics-heavy games, for instance — require. And you forgo the app store as a discovery and credibility channel, which matters in some markets.

When a PWA is worth it

Content, services and ecommerce

If your app is essentially about browsing, reading, booking or buying, a PWA usually delivers everything users need. Many online retailers use PWAs to give shoppers a fast, app-like experience without forcing a download — and see better engagement for it.

You want reach without the store barrier

Every step between discovery and use loses people. A PWA removes the download barrier entirely, which can mean far more people actually using your service.

Budget and speed matter

If maintaining separate native apps is beyond your budget, a PWA gets you a strong app-like experience for considerably less.

When to go native instead

Choose a native app when you genuinely need deep device integration, maximum performance, or the app store as a core discovery and trust channel. Apps central to a product, or those relying on advanced hardware features, are usually better native — particularly given iOS's tighter limits on PWAs.

A useful rule of thumb: if your 'app' is really a fast, installable version of your website, a PWA likely fits. If it needs to do things only a phone's deeper hardware allows, lean native.

So, are they worth it?

For a large share of UK businesses — especially in content, services and ecommerce — a PWA is absolutely worth it: app-like benefits, broad reach, and meaningfully lower cost than going native. For those needing peak performance or deep device features, native still earns its higher price. The wrong move is choosing either based on hype rather than what your users actually need to do.

The honest answer depends on your specific goals, audience and budget. Brief two or three providers, describe what you want users to be able to do, and compare their recommendations. Experienced app development specialists in our directory can tell you whether a PWA, a native app, or a combination makes sense — and what each would realistically cost — before you commit a penny.
