What Is A PWA And How Does It Work?

A Progressive Web App (PWA) can be clearly defined as a website built by integrating modern web capabilities that allow it to perform like a native app on smart devices. A few of its most prominent features are mentioned further.

• Users can easily install it and use it on their mobile phones directly through a browser rather than depending on the App Store.
• It requires service workers to operate offline or collaborate with flaky networks.
• It offers fast-performing page speed optimisation and easily sends push notifications through high-level caching.
• It is a cross-platform app that uses a single code base for desktops, smartphones, and tablets.

Most experts define PWA as the middle ground between A native app and a mobile-optimised website, fortunately. It is the best combination of both these platforms, without the need to develop different apps for IOS and Android. For this reason, business owners looking for a market-fit digital product often invest in PWAs.

The Business Case In 2025: Cost, Speed, And Reach

Most startups pay attention to speed and runway on their platforms.  Interestingly, PWAs deliver value on both sides easily.

Market Momentum & Growth

When focusing on the industry market, experts estimate that the PWA market is expanding rapidly.  Different analysts have projected multibillion-dollar growth through the 2020s.  These forecasts are a true reflection of steady adoption across popular industries like retail, media, and travel.

Lower Total Cost of Ownership (TCO)

There is no doubt that the development and maintenance of a single PWA code base is prominently considered cheaper than investing in separate native apps for both Android and iOS.  According to the analysis of different agencies and reports, reduced development time and maintenance are consistently highlighted as a key tool that drives startups operating through PWAs.

Faster Time to Market

Professionals must understand the importance of early-stage testing and user feedback loops as a critical step. Interestingly, with a single code base, shipping iterative improvements is easier. Founders who keep searching and pitching investors can consider a functioning PWA MVP as the finest way to showcase their traction in a short time.

SEO & Discoverability

Progressive web apps are web-first platforms, which means they can be easily indexed by search engines. As a result, target audiences can easily find your product through Google search without the need to pass through the discoverability funnel of app stores.

This helps in reducing acquisition friction, especially considering London startups that are competing to earn a higher position in organic channels.

Key Stats to Quote:

• According to Grand View Research, the global PWA market is projected to grow from USD 2.08 billion in 2024 to USD 21.24 billion by 2033.
• According to a detailed survey of the first quarter of 2025, PWAs result with an approx. 43% lower bounce rate than comparable mobile websites, and users see a 70% increase in session length along with 20% more page‑views.

Startup-Friendly PWA Features That Matter Most

Below, we have shared a few practical PWA features that directly impact the growth of our business.

• The app must be installable on the home screen.

It gives users a chance to add the app quickly to their smart devices with fewer barriers, unlike an app that must be downloaded from the App Store.

• The app should include offline caching.

This way, users get a chance to use the app while it is offline, which directly increases the number of revisits.

• The app should offer push notifications.

It is a great way to re-engage potential customers with offers, reminders, and the different transactional updates.

• The app must have a fast-loading speed.

Apps with a quick first load and repeat load speed are sure to provide better conversions and lower bounce rates.

• The app needs to run on a single code base.

It is one of the easiest ways to generate unified analytics with faster iteration.

• The app must include an SEO friendly landing page.

It benefits the app with more organic searches, which is almost impossible to achieve by native apps.

PWA vs Native: Comparison by Experts

QUICK COMPARISON TABLE

It clearly explains that you can choose PWA when you want fast validation, lower cost, and broader reach. Native apps, on the other hand, become an option when you need tight hardware integration, store-driven discovery, and extremely high performance.

Technical Limits and Browser Support

Just like any other device, PWAs have their own limitations.  Professionals must be aware of these considerations.

iOS Limitations:

Safari’s PWA support offers lower performance compared to Chromium browsers. Therefore, users must know that some API's like advanced push features and background tasks, can be limited.  It is necessary to test cross-platform behaviour.

Push Notifications On iOS:

Push notifications are gradually supported on iOS devices because iOS support can be more restricted than Android.  Developers must prepare for fallbacks during critical notifications.

Hardware Access:

It is necessary to know that different advanced sensors, payment gateways, or Bluetooth peripherals still support native apps.  Investors must prepare a list of must-have device API before starting any process.

Perception:

The perception of users is necessary because many individuals still consider App Store presence the key factor to call it a “real app”.  Owners who invest in good onboarding and excellent user experience quickly reduce this friction.

Practical Tip: The best tip is to build an analytics-driven feature list.  Professionals must prioritise re-evaluation rather than postponing it in cases where a hardware API or OS specific feature is mandatory.

When To Evolve from PWA To Native?

Most professionals will easily know the right time to invest in native apps. Beginners can judge it from one of the following situations.

• Your target audiences start demanding advanced-level device features that are unavailable through web API’s.
• Your business consists of an extensive and engaged user base that benefits from native performance.
• App Store presence becomes a key requirement for discoverability and scalability.
• You are planning to extend your platform, and the product road map is in consistent need of platform-level integrations.

Most often, the pragmatic root starts from PWA and moves toward validation, which converts high-value users into natives later. Moreover, some companies also maintain shared back ends and separate native front ends as soon as they can justify the extra cost of clear revenue and engagement.
