Offline-first

Fast like apps, accessible through browser.

Progressive Web Apps combine best features of sites and applications. Work offline, install on home screen, and send notifications – without App Store.

Browser installation
Offline mode
Push notifications

Mobile app isn't only option.

Store commissions

App Store and Google Play take 15-30% of transactions. PWA bypasses stores – no commissions.

Installation barrier

Users don't want to download more apps (70+ MB). PWA is one click 'Add to home screen'.

Long review

Apple/Google check updates 2-5 days. PWA updates immediately after deployment.

Platform lock-in

Native app requires separate code for iOS and Android. PWA works on any device with browser.

High development costs

Writing 2 applications (iOS + Android) is 2x time and budget. PWA is one codebase.

SEO and reach

Mobile apps are invisible to Google. PWA indexes like normal website.

Web tech

What do you get with PWA?

Full-fledged application accessible through browser. Installed on home screen, working offline, and sending notifications.

Service workers cache resources – app works even without internet.

05

Maintenance and updates
