Progressive web apps for fashion: when to build PWA versus native app
PWAs cost 40 to 60 per cent less to build than native apps and deliver faster time to market, but native apps still outperform on push engagement and device integration.

KEY TAKEAWAYS Summary by the editors
- PWA development costs range from 25,000 to 80,000 dollars, compared to 80,000 to 200,000 dollars for native apps covering iOS and Android.
- Fashion brands including Mainline Menswear, Eleganza and TALLY WEiJL report conversion rate increases of 55 per cent, 76 per cent page growth and 140 per cent respectively after PWA launches.
- iOS PWAs gained push notification support in iOS 16.4 but require manual home screen installation and face a 50 megabyte cache limit on Safari.
- Native apps deliver higher retention and push engagement but require separate development for each platform and app store approval for updates.
Fashion retailers choosing between a progressive web app and a native mobile application face a trade off between cost and capability. PWAs typically cost 25,000 to 80,000 dollars and ship in four to eight weeks, whilst native apps covering iOS and Android run 80,000 to 200,000 dollars or more over six to nine months. PWAs offer cross platform compatibility at 50 to 70 per cent lower development costs than native apps, but native apps still deliver two times higher push notification engagement and 15 to 20 per cent faster rendering.
What capabilities do PWAs and native apps each provide?
Progressive web apps are websites built with modern web standards that install directly from the browser without an app store. Push notifications, background sync, biometric authentication and offline first architecture are now fully supported across Chrome, Safari and Edge. Native apps remain platform specific applications downloaded from app stores with full access to device hardware.
PWA iOS limitations are restrictions that Apple's Safari browser and iOS impose on progressive web apps, blocking access to device features, background tasks and system integrations that native iOS apps can use freely, though iOS 16.4 brought push notification support. If a user does not open a PWA for a week all cached data is gone, and Safari caps storage at 50 megabytes compared to hundreds of megabytes on Chrome. Safari gained Web Push in iOS 16.4 but still cannot use Bluetooth, NFC or Background Sync as of 2026.
Native apps provide full offline storage, complete access to camera, Bluetooth, NFC and biometrics, and reliable background processing. Native app conversion rates average 3.5 per cent against 3.0 per cent for PWAs and 2.1 per cent for responsive mobile web, whilst push notification opt in reaches 52 per cent for native apps compared to 38 per cent for PWAs.
How do fashion retailers use PWAs in practice?
SHEIN, the online fashion marketplace, runs its mobile website at m.shein.com as a PWA that installs on the home screen under the SHEIN name. Mainline Menswear achieved a 55 per cent higher conversion rate than its regular website after adding PWA features, whilst TALLY WEiJL experienced a 131 per cent increase in mobile revenue, a 140 per cent rise in conversion rate and a 45 per cent growth in page views following its PWA introduction.
Eleganza, a high end fashion retailer in the Netherlands, transitioned to Magento 2 with a PWA storefront after discovering 90 per cent of their customers browsed on mobile devices. Results included a 76 per cent increase in pages per session, 23 per cent faster average page load time and 372 per cent faster average server reaction time. Fashion brand Rooted Objects reports a 162 per cent increase in conversions after the launch of its PWA sites, with page load times dropping by 25 per cent and average redirection time falling by 80 per cent.
Next, a British omnichannel clothing, footwear and home products retailer, focused in 2025 on replatforming its mobile commerce offering to a native app, illustrating that some established retailers continue to choose native development for their primary mobile strategy.
What are the cost and maintenance differences?
Development expenses diverge significantly. Initial build costs range from 30,000 to 80,000 dollars for PWAs, 120,000 to 250,000 dollars for native iOS and Android, and 80,000 to 180,000 dollars for cross platform native frameworks, whilst annual maintenance runs 10,000 to 25,000 dollars for PWAs against 40,000 to 80,000 dollars for dual platform native apps.
| Factor | PWA | Native app |
|---|---|---|
| Build time | 2 to 4 months | 5 to 9 months |
| Platform coverage | Single codebase | Separate iOS and Android |
| App store fees | None | 99 dollars yearly Apple, 25 dollars once Google |
| Update distribution | Instant | App store approval required |
| SEO indexing | Fully indexed | Not indexed |
PWAs are built using a single codebase, which lowers both development and maintenance costs by 35 to 50 per cent. Ongoing maintenance costs typically represent 15 to 25 per cent of initial development costs annually, which is generally lower than native app maintenance requirements.
How do conversion and engagement compare?
Mobile web visitors generate 2.10 dollars average revenue, PWA visitors 3.45 dollars and native app users 5.80 dollars, but native app user acquisition cost runs 3 to 8 dollars per install. When acquisition cost is factored in, PWAs often deliver higher return on investment for businesses without an established loyal mobile customer base.
Junior Couture, a luxury childrenswear brand on Salesforce Commerce Cloud, saw only about 5 per cent of users on the app during Black Friday Cyber Monday 2025, but those 5 per cent contributed around 50 per cent of total sales for the period. Fashion brands that launch mobile apps see 3 to 10 times higher revenue per user compared to mobile web.
The PWA from Debenhams brought a 40 per cent boost in mobile revenue and a 20 per cent increase in conversion. The Debenhams online store became 4 times faster than before, with revenue increasing by 40 per cent and mobile conversion rising 20 per cent after the PWA build completed in four months.
When should fashion brands choose PWAs?
Progressive web apps suit retailers prioritising speed to market, broad reach and lower investment. Businesses with fewer than 500,000 monthly mobile visitors should start with PWA. PWAs work well when customers arrive primarily through search, social media or email rather than app store discovery.
Fashion brands benefit from PWA offline browsing during commuting, faster loading on slow connections and instant updates without app store approval cycles. Fashion brands can increase mobile conversion by 30 to 40 per cent just by implementing a PWA, and can reach out to a great number of users already engaged in social media whilst ensuring their seamless transfer to transaction sites.
The technology fits content driven strategies, frequent product launches and markets with lower end devices or limited storage. The PWA uses only 100 kilobytes of storage versus 10 megabytes or more for a native app, which is critical in markets where device storage is limited.
When should fashion brands choose native apps?
Native applications make sense for brands with established customer bases seeking maximum retention and engagement. PWAs have closed much of the experience gap for standard ecommerce journeys and offer faster iteration, broader reach and lower surface area complexity, whilst native apps still make sense where deep OS integration, loyalty led engagement or in store workflows create clear business value.
Retailers requiring augmented reality try on, NFC payments, complex offline workflows or tight integration with physical retail systems need native capabilities. Native apps only offer additional value when you need deep device integration including AR try on, NFC payments and complex offline workflows, or when your brand has the traffic and loyalty to justify the 50,000 to 300,000 dollar or more native app development cost.
Brands for whom app store presence drives meaningful discovery and credibility also favour native development. App store presence matters when a listing in the App Store and Play Store is a discovery and trust signal a PWA cannot replicate, as shoppers who search the stores for your brand will not find a PWA there.
A sound low risk path for many products is to ship a PWA first as it is the fastest way to get a real product in front of real users, costs the least and tells you whether demand is there, then build the native app when usage proves out and a concrete native only need appears.
Frequently asked questions
How much does it cost to build a PWA for a fashion retailer compared to a native app?
PWA development typically costs 25,000 to 80,000 dollars with annual maintenance of 10,000 to 25,000 dollars, whilst native apps covering iOS and Android cost 80,000 to 200,000 dollars or more to build with annual maintenance of 40,000 to 80,000 dollars. PWAs use a single codebase that lowers development and maintenance costs by 35 to 50 per cent compared to separate native platforms.
Can PWAs send push notifications on iPhone?
Yes, but with restrictions. PWAs can send push notifications on iPhone from iOS 16.4 onwards, but only after someone adds the site to their home screen and then allows notifications. Safari never prompts people to install a PWA, so every install depends on users finding Add to Home Screen in the Share menu. Safari also caps PWA storage at 50 megabytes and deletes cached data if the PWA is not opened for a week.
Which fashion brands have successfully launched PWAs?
SHEIN runs its mobile website as an installable PWA. Mainline Menswear achieved a 55 per cent higher conversion rate after adding PWA features. TALLY WEiJL saw a 131 per cent increase in mobile revenue and 140 per cent rise in conversion rate. Eleganza reported 76 per cent more pages per session and 23 per cent faster load times. Rooted Objects achieved a 162 per cent increase in conversions with page load times dropping 25 per cent.
