Softomate Solutions is a London-based software development company specialising in mobile and web application development for UK businesses. When clients come to us wanting a mobile experience, one of the first questions we work through together is whether a progressive web app (PWA) or a native app is the right choice. Both are legitimate solutions. The right answer depends on your users, your budget, your timeline, and what you need the app to do. Getting this decision wrong early costs significantly more to correct later.
A progressive web app is a website built with modern web technologies that behaves like a native mobile application. It can be added to a phone's home screen, works offline using cached data, sends push notifications, and loads instantly from subsequent visits. PWAs are accessed through a browser and can be installed without going through the App Store or Google Play. The technology is supported in all major browsers and is used at scale by companies including Twitter, Starbucks, and the UK's own Financial Times.
The core PWA technologies are service workers, which handle offline caching and background sync; a web app manifest, which defines how the app appears when installed; and HTTPS, which is mandatory for service worker registration. A PWA that is well-built is indistinguishable from a native app in normal use. A PWA that is poorly built is slower and less reliable than a simple website - the technology creates the possibility of a great experience, but the quality of execution determines whether that possibility is realised.
PWA adoption among UK businesses has grown significantly since 2020. The combination of improving browser support, better tooling, and a growing awareness of app store commission costs has made PWAs a serious option for a much broader range of use cases than they were when the technology was first standardised. Major UK retailers, banks, and media companies have invested in PWA development as their primary mobile channel.
A native app is built specifically for a single platform - iOS using Swift or Objective-C, Android using Kotlin or Java - and distributed through the App Store or Google Play. Native apps have direct access to device hardware and operating system APIs, which gives them the best possible performance and the deepest integration with platform features such as Face ID, ARKit, advanced camera controls, and background processing.
Cross-platform frameworks like React Native and Flutter sit between PWAs and fully native apps. They use a single codebase that compiles to native code for both iOS and Android, giving near-native performance while reducing development time. Our mobile app development service covers both fully native builds and cross-platform development, and we recommend the right approach based on specific client requirements rather than technology preference.
Native apps carry higher development and maintenance costs but deliver the best-in-class experience on each platform. For consumer products in highly competitive markets - fitness, finance, gaming, social - where the quality of the mobile experience is a primary differentiator, native development remains the standard. For business applications, productivity tools, and services where functionality matters more than experience polish, the native advantage is often insufficient to justify the additional cost.
Native apps consistently outperform PWAs on raw performance benchmarks. This matters most for graphically intensive applications - games, augmented reality, real-time video processing - where the app needs to push the hardware. For the majority of UK business applications, however, the performance difference is imperceptible to users. A well-optimised PWA serving a booking flow, a dashboard, or a catalogue browser will feel just as responsive as its native equivalent.
PWA performance has improved dramatically since 2020. Google's Core Web Vitals programme has incentivised developers to build faster, lighter web experiences, and the tools available for PWA optimisation - lazy loading, code splitting, image compression, service worker caching strategies - are mature and well-documented. A PWA built to Lighthouse standards will score above 90 on performance metrics and will load in under two seconds on a 4G connection.
Where PWAs lag is in background processing. Service workers are constrained by the browser's energy management policies, which means tasks like syncing large datasets in the background or processing sensor data continuously are better suited to native apps. For web application development that does not require continuous background processing, a PWA is a very strong choice. The relevant question is not whether native is theoretically faster, but whether the performance difference is detectable in the actual use cases your users have.
JavaScript engine performance, which underpins PWA execution, has improved dramatically across mobile browsers. The V8 engine in Chrome and the Nitro engine in Safari are both significantly faster than they were three years ago. For computationally light-to-medium tasks - the kind that make up most UK business application functionality - modern PWAs are indistinguishable from native apps in user experience terms.
Native apps require App Store and Google Play distribution, which has significant implications for UK businesses. Apple takes a 15 to 30% commission on in-app purchases and subscriptions, which materially affects the economics of any app that monetises through the platform. The App Store review process typically takes one to five business days and can result in rejection if guidelines are not followed, which delays launch. Updates to native apps must also pass review, meaning a critical bug fix may take one to five days to reach users.
PWAs bypass the app stores entirely. They are accessed through the browser, which means there is no commission, no review process, and no waiting period for updates. When you fix a bug or release a new feature in a PWA, all users see it immediately - there is no version fragmentation where some users are on an old version because they have not updated. For UK businesses that ship updates frequently or respond quickly to market changes, this is a significant operational advantage.
For UK businesses considering monetisation, the app store commission is a substantial factor. A subscription product charging ยฃ9.99 per month that processes payments through the App Store pays Apple ยฃ1.50 to ยฃ3.00 per subscriber per month. On 1,000 subscribers, that is ยฃ18,000 to ยฃ36,000 per year going directly to Apple. Processing the same subscription through a web payment provider like Stripe, which a PWA can use directly, costs approximately 1.4% plus 20p per transaction - a fraction of the platform commission. The UK's Digital Markets, Competition and Consumers Act 2024 is beginning to challenge app store monopoly practices, but the commission structure remains intact for now.
The gap between PWA and native device access has narrowed considerably. Modern PWAs on Android can access the camera, microphone, geolocation, push notifications, biometric authentication via WebAuthn, clipboard, Bluetooth, and USB. On iOS, support is more limited - Apple has been slower to expose device APIs to the web, though support has improved significantly with each Safari release since iOS 16.
PWAs on iOS currently cannot access the NFC chip, background app refresh, or advanced camera controls like RAW capture. If your application requires NFC payments, contactless access control, or professional photography features, a native iOS app is the right choice. If it requires none of those, the PWA feature set is likely sufficient.
A practical test for any UK client: list every device feature your application needs. If all of them are supported by both Android and iOS web APIs, a PWA can deliver the full experience. If one or more require native access, evaluate whether the affected features are core to the product or can be handled differently. Frequently, the features that seem to require native access turn out to have web alternatives that are adequate for the actual use case.
The Project Fugu initiative from Google, Microsoft, and Intel has been systematically adding powerful capabilities to the web platform. File system access, serial port communication, advanced clipboard operations, and shape detection are among the capabilities added to Chrome in recent years. This trend is likely to continue narrowing the gap between PWA and native capability over time.
PWAs cost significantly less to build and maintain than native apps. A PWA requires one codebase that works across every device. A native app requires separate codebases for iOS and Android, or a cross-platform framework that still requires platform-specific adjustments and testing on both stores. The development cost difference is material: a PWA typically costs 40 to 60% less than a comparable two-platform native build when measured on total development hours.
Maintenance costs compound over time. Every OS update from Apple or Google requires native apps to be tested and often updated. iOS 17 and 18 both required changes to apps using certain APIs. A PWA running on web standards is far more stable because the web platform evolves more slowly and with stronger backwards compatibility guarantees. The annual maintenance overhead for a mature native app is typically 15 to 25% of original development cost. For a comparable PWA it is closer to 5 to 10%.
For UK startups and SMEs working within budget constraints, a PWA is often the sensible first deployment. It gets a product in front of users quickly and cheaply. If usage patterns reveal a need for native features - a specific device capability, deeper performance, or app store discoverability - a native app can be built for the most important platform, informed by real user data rather than assumptions. The common path for UK scale-ups is PWA first, then a native iOS app once the product-market fit is established and the iOS user concentration justifies the investment.
Choose a PWA when your users are primarily on Android, your application does not require deep device hardware access, you want to avoid app store commissions, and you need to deploy and update quickly. PWAs are excellent for dashboards, booking systems, service catalogues, internal tools, field service applications, and content platforms. Many of the most effective UK enterprise tools built in the past three years are PWAs rather than native apps.
Choose a native app when your users skew heavily towards iOS, your application requires NFC, advanced camera controls, or continuous background processing, you need App Store discoverability as a growth channel, or your product's core value proposition depends on a deeply integrated device experience. Consumer social apps, mobile games, and applications that rely on advanced hardware capabilities belong in this category.
Choose a cross-platform framework - React Native or Flutter - when you need native-quality performance on both iOS and Android but want to share as much code as possible and reduce development costs. This is often the right answer for UK businesses building a consumer-facing product that genuinely requires native device features. Flutter in particular has matured significantly and now produces near-native performance with a single codebase.
Our mobile app development team in London helps clients make this decision as part of our Discovery process, so the choice is based on your specific user research, technical requirements, and business model rather than generic advice. The right decision in 2024 for a UK logistics business is different from the right decision for a UK consumer fintech, and we have experience across both.
One consideration that is often overlooked is the internal team's capability to maintain and evolve the product after launch. If your organisation has web developers in-house, a PWA is far easier for them to understand and contribute to than a native codebase. If your team is mobile-native, a React Native or Flutter codebase is approachable. Choosing a technology that your internal team can work with reduces dependency on external agencies for routine updates and lowers the long-term total cost of ownership for the product.
Testing strategy differs meaningfully between PWAs and native apps. PWAs can be tested with standard web testing tools - Playwright, Cypress, Lighthouse - across browsers without device simulators. Native apps require testing on real devices across a range of OS versions and screen sizes, using Xcode simulators, Android emulators, and physical device farms. The testing overhead for a two-platform native app is considerably higher than for a PWA, and this cost should be factored into both the build estimate and the ongoing maintenance budget.
PWAs can be listed on Google Play using a wrapper called a Trusted Web Activity (TWA), which packages the PWA in a thin Android shell that passes Play Store review. Apple does not support TWAs on the App Store. For full App Store presence on iOS, a native or cross-platform app is required. Many UK businesses choose to list on Google Play via TWA while keeping the iOS experience as a browser-accessible PWA, capturing the Android app store audience without building a separate codebase.
Yes. PWAs use service workers to cache content and data, which allows core functionality to work without an internet connection. The degree of offline capability depends on how the service worker is configured. A well-built PWA can cache recent content, queued actions, and user data so that a commuter going through a tunnel or a field worker in a low-signal area experiences minimal disruption. Full offline capability requires careful data architecture - not all applications are suited to it, and the trade-offs between offline data freshness and storage efficiency must be designed explicitly.
PWAs run over HTTPS, which is a requirement of the service worker specification. Modern web security standards - Content Security Policy, Subresource Integrity, CORS, WebAuthn biometric authentication - make PWAs suitable for regulated UK applications. Both the FCA and NHS Digital technical guidance acknowledge web-based delivery as compliant for many application categories. Specific requirements for data storage, encryption, and audit logging should be reviewed against your regulatory obligations with legal and compliance advisers.
A PWA for a defined business application typically takes twelve to eighteen weeks to build. An equivalent native app for a single platform (iOS or Android) takes sixteen to twenty-four weeks. A two-platform native build takes twenty to thirty weeks. A cross-platform build using React Native or Flutter covering both iOS and Android typically takes eighteen to twenty-six weeks. All timelines include Discovery, design, development, testing, and deployment phases.
Yes, though the effort required depends on the existing site's architecture. Adding PWA capabilities to a modern JavaScript-based site - a manifest file, a service worker, HTTPS - can be done in a few days. Retrofitting PWA capabilities to a legacy site with poor performance, inconsistent markup, and server-side rendering requires more substantial work, often including a performance audit and a partial rebuild. Our team can assess your existing site and give a realistic estimate of the work involved.
