Web apps and PWAs vs. mobile apps: what's the difference and which one fits you

You want an app. Your customers are asking for a smooth mobile experience, your competitors are already there, and you face the question that decides the budget, the timeline and the pace of growth: a web app or PWA versus a native mobile app. The difference isn't just technical; it's a business difference, and the wrong choice costs you money and months of unnecessary development.

It is also the first decision in any app development project for a business, so it is worth coming to it with a clear picture. In this guide we break down the differences in full, in business owners' language: what each option gives you, what it costs, where it falls short, and how to choose.

What is a web app, anyway, and why is everyone talking about PWAs?

A web app is software that runs in the browser. There is no store download, no installation file, no waiting for Apple's or Google's approval. The customer clicks a link or scans a QR code, and the app opens right away. Unlike a static brochure site, a web app is interactive and full of functionality: user login, a shopping cart, a personal dashboard, appointment booking, chat, all inside the browser.

A PWA, short for Progressive Web App, is the more advanced generation of the web app. It is a web app that has gained capabilities once reserved for native apps: you can add it to the phone's home screen with its own icon, it opens full screen without the browser bar, and it can send push notifications. Thanks to a component called a Service Worker, which stores files and data in the cache, it keeps working even when reception is poor or nonexistent, for example in an elevator or on a flight. In other words, a PWA looks and feels like an app, but under the hood it is a web app running in the browser.

The magic of the Progressive Web App is that it bridges the historic gap between a website and an app. Until recently, the choice was clear: if you wanted access from any device, you built a website, and if you wanted an icon on the screen, notifications and offline use, you built a native app. Today you can get a large share of those capabilities from a single codebase that runs in the browser. You'll find a full description of these capabilities in Google's explanation of PWAs on web.dev.

A native mobile app: what it gives you and what it costs

A native app is software written specifically for the device's operating system. An iPhone app is built in Apple's languages, an Android app in Google's, and the user downloads it from the App Store or Google Play. This is how the apps we all know were built, and it has real advantages that should not be dismissed.

A native app gets full, direct access to all of the hardware's capabilities: an advanced camera, motion sensors, precise GPS, Bluetooth, a fingerprint reader, file management and a deep offline mode. Its performance is especially high in heavy tasks such as 3D games, video editing or real-time graphics processing. In addition, a presence in the app stores brings exposure and trust: some customers look for you directly in the store, and a high rating with good reviews is a marketing asset.

The price of all this is double, in both senses of the word. First, true native development requires two separate systems, one for iPhone and one for Android, which doubles the work hours. Second, every update has to go through the stores' approval process, and their policies can delay or reject your app. The cost gap between a PWA and a full native app can be very significant, which is why it is important to choose with your eyes open.

Web app vs. native: the comparison that settles the decision

To make a well-considered decision, it helps to put the two worlds side by side on the factors that really affect the business:

• Development cost: web apps and PWAs have a clear advantage. One codebase serves every device, so the cost and the time are significantly lower than double native development.
• Distribution and installation: a PWA has no barriers. You send a link, and the customer is in. A native app requires a search in the store, a download and an installation, and every one of those steps loses some users along the way.
• Updates: with a PWA, an update goes live for all users the moment you publish it. With a native app you have to wait for the store's approval and hope the user updates.
• Payments: with a PWA, payment goes through your own payment processor. In an app from the store, selling digital content inside the app is subject to the store's commission.
• Hardware access and heavy performance: this is where native wins. If you need advanced image processing, augmented reality or game-level performance, this is its home turf.
• Store discovery: an advantage for native. A presence in the App Store and Google Play is a channel of exposure and trust in its own right.
• Ranking on Google: a big advantage for the web app. A web app is indexed and appears in search results, while the content of a native app is not crawled as pages on Google.

Pay attention to that last point, because it is often forgotten. A web app is also an SEO asset: every public page in it, such as service pages, product pages and articles, can appear on Google and bring in free traffic, and the Service Worker's cache makes repeat visits very fast. The condition is that the content of the public pages comes from the server as complete HTML and isn't built only in the browser, while personal areas behind a login aren't meant to be indexed anyway. You'll find exactly what to check on the technical side in the checklist for building an SEO-friendly website. For a business that relies on organic SEO as a channel for acquiring customers, this is a significant consideration in favor of the web app.

The big advantages of a PWA for an Israeli business

For most businesses in Israel, especially small and medium-sized businesses, early-stage startups and service companies, a PWA is usually the smart starting point. Here's why:

A low price and a short development time

Instead of funding and maintaining three separate versions (a website, an iPhone app and an Android app), you fund one product that works everywhere. That dramatically lowers the barrier to entry and lets you launch fast, test the market and grow gradually. For a restaurant owner who wants an ordering app, or a clinic that wants an appointment system, there is no reason to spend a full native budget in the first stage.

Zero friction on the way to the customer

Every step where the customer has to stop and act is a drop-off point. A search in the store, a permissions screen, a download of dozens of megabytes: all of these drive customers away. With a PWA you send a link on WhatsApp, the customer clicks, and within a second they're in. For an Israeli business whose traffic comes mostly from WhatsApp, Instagram and paid ads, this is a fundamental change in conversion rates.

Notifications and a home screen icon without a store

A modern PWA can send push notifications, install itself on the home screen and work offline too. In other words, you get the lion's share of a native app's advantages without the cost and the dependence on the stores. The customer sees an icon on their screen, taps it, and it opens just like any other app. On iPhone there is one condition worth knowing: push notifications have been supported since iOS 16.4, and only after the user has added the app to the home screen and allowed notifications.

Payments without a store commission

In an app distributed through the App Store or Google Play, selling digital content or a digital service inside the app, such as a subscription or paid content, usually goes through the store's payment system, which takes a commission on every transaction. At Apple, for example, even in the Small Business Program the reduced commission is 15%. With a PWA, payment goes through your own payment processor, with no commission to the store. It is also important to know the other side: under the App Store Review Guidelines, physical goods and services consumed outside the app, such as a food delivery or a treatment appointment, are paid for with regular payment methods anyway, not through Apple's in-app purchase system. So for a business that sells a physical product or a service, the commission consideration is less decisive, and for a business that sells digital content it can decide the whole question.

The limits of a PWA: when it isn't enough

Professional honesty means telling the other side too. A PWA is an excellent tool, but it is not a solution for every scenario. There are cases where a native app is the right choice, and trying to force a PWA into them is a mistake.

• Deep hardware access. If your product relies on advanced sensors, augmented reality, complex Bluetooth or heavy video processing, native will deliver performance and flexibility that are hard to achieve in the browser.
• iOS limitations. Apple has historically limited some PWA capabilities on iPhone. Push notifications are supported only after the app is added to the home screen, and installation itself happens through the browser's share menu rather than with a single button tap as on Android. The gap has narrowed a great deal, but if most of your audience is on iPhone, check in advance that the capabilities you need are supported.
• Store presence as a marketing channel. If your business model is built on discovery in the App Store, ratings and reviews, or on payments through the store, you'll need a native presence.
• Games and heavy graphics. For resource-intensive real-time experiences, native still leads.

The good news is that here, too, it doesn't have to be all or nothing. There is an excellent middle approach, cross-platform development, in which you write one codebase and get an app that compiles to truly native code for both iPhone and Android. We covered this in depth in the separate guide on native vs. cross-platform apps, and it is required reading before you make a final decision.

How to make the right choice: four deciding questions

Before you commit to a direction, answer four questions for yourself honestly. The answers will point the way almost every time:

1. Where do my customers come from? If most of the traffic comes from links, WhatsApp, paid ads and Google, the web app and the PWA will win thanks to zero friction. If most of your audience looks for apps in the store, consider native.
2. What are the budget and the timeline? If you want to launch fast and smart without burning your budget, a PWA is the choice. Double native development is a bigger investment of time and money.
3. What does the app need to do technically? Content management, orders, a personal profile, payments and notifications are an excellent fit for a PWA. Heavy hardware processing tips the scales toward native.
4. What happens after launch? If you expect frequent updates and want flexibility, a PWA that updates instantly saves you a lot of headaches with the stores' approval processes.

There is no single answer that is right for everyone. There is an answer that is right for you, and it follows from the business model, the audience and the budget. That is exactly why the specification stage exists: on the VeloLinx development team, we start every project by understanding the business goal, and only then recommend an architecture. If you're not yet sure your business needs an app at all, start with the seven questions that will help you decide, and if the decision has already been made, continue to the guide on how to develop an app from A to Z.

How much it costs and what it depends on

The price of developing an app varies widely, and there is no single number that fits every project. Instead of pulling a price out of thin air, here are the real factors that set the budget, so you know what you're paying for:

• The scope of features. A simple appointment app is completely different from a marketplace platform with payments, vendor management and complex logic.
• User experience design. A custom interface, careful branding and animations require more work than a ready-made template.
• Integrations. Connecting to payment processing, a CRM system, WhatsApp or existing management systems: each one adds work.
• Native vs. PWA. As we saw, double native development costs more than one web app that serves every device.
• Maintenance and what comes next. An app is a living product, and a smart budget accounts for updates and support too.

As a rule of thumb, a PWA lets you get into the game with a significantly lower investment and grow gradually, and that is what makes it so attractive to businesses that want a fast return. Every quote we give is tailored to the specific project, after we understand what you really need. You'll find a breakdown of the factors and the ranges in the pricing guide for developing an app. And if along the way it turns out you also need a brochure website or a broader web system, it is worth getting to know our website development for businesses service.

Frequently asked questions

What exactly is a PWA, and how is it different from a regular web app?

A PWA, or Progressive Web App, is a web app that has gained advanced capabilities: installation on the home screen, offline mode and push notifications. A regular web app runs in the browser and needs a connection, while a PWA feels and works almost like a native app, with no store and no download.

Do PWAs work well on iPhone?

Yes, with a few caveats. You can install a PWA on the home screen through the browser's share menu, and since iOS 16.4 it can also send push notifications, provided the user has added it to the home screen and allowed notifications. If most of your audience is on iPhone and you need specific capabilities, it is worth checking them as early as the specification stage.

Does a PWA work offline?

Yes, to the extent it was planned in advance. The Service Worker caches the screens and data that have already loaded, so you can open the app and browse them even without reception. Actions that need a server, such as a payment or booking an appointment, wait for a connection or are saved and sent when the connection returns.

When is it better to choose a native app over a PWA?

Native is better when you need deep hardware access such as advanced sensors or augmented reality, heavy performance such as games, or when a presence in the App Store and Google Play is a main marketing channel for you. For most service, commerce and appointment-based businesses, a PWA is an excellent solution at a lower cost.

Do you have to pay Apple or Google a commission on a PWA?

No, as long as the PWA is distributed through the browser and not through the stores. Payments go through your own payment processor, and there is no store commission on subscriptions or on digital content. If you later choose to publish the app in a store as well, that store's payment rules will apply to it.

Does a web app help me rank on Google?

Yes, and it is a big advantage. The public pages of a web app or PWA are indexed by search engines and can bring in organic traffic, provided their content comes from the server as complete HTML. The content of a native app, by contrast, is not crawled as pages in the search results, and what appears on Google is at most the app's page in the store.

Can you start with a PWA and move to native later?

Absolutely, and it is usually the smartest strategy. You start with a PWA to launch fast, test the market and learn from users at a reasonable cost, and only if the need justifies it do you add a focused native version. That way the budget goes where it really creates value, and the server-side logic serves both versions.
