SPA / PWA app

A SPA (Single Page Application) is a site that behaves like an app: screen transitions happen without reloading the page, instantly. A PWA (Progressive Web App) adds app capabilities: installation on a phone with a home-screen icon, offline mode and push notifications — but without publishing to the App Store or Google Play. It is not just another large website but an app in how it feels: it fits services, user accounts, dashboards and interactive interfaces where speed and responsiveness matter.

• A regular site is slow: every action reloads the page, the user waits and gets frustrated.
• You need an app, but building separately for iOS and Android plus store publishing is expensive and slow.
• The service does not work without internet and never reminds users about itself — they forget to come back.
• The interface is complex (filters, forms, calculations), and on a regular site it lags and is awkward.

• App interface design: screens, states, scenarios without reloads
• SPA development on a modern framework (React or Vue) with instant navigation
• PWA features: install on a phone, add to home screen, offline mode (limited cache) and caching — tailored to your scenarios
• Push notifications (web push), with user consent, to bring the audience back
• Connection to API and backend: data, authentication, user account (1C, CRM and external integrations by agreement)
• App-like UX: smooth transitions, instant response, mobile-first layout
• Speed optimization: fast initial load, lazy data loading
• SEO foundation for SPA: prerender or server-side rendering of key pages for indexing (scope agreed per project)

• A web app that opens instantly and works without reloads
• Installs on a phone like an app — without the App Store or Google Play
• Works offline within the cache and brings users back through push notifications
• One codebase for the web version across platforms — cheaper and faster to launch than separate native apps for iOS and Android

• You leave a request and describe the service and user scenarios
• We design the screens, logic and data connections and fix the scope of integrations
• We build, test on devices and launch the app

• How is a PWA different from a regular mobile app?

  A native app is downloaded from the App Store or Google Play and built separately for each platform. A PWA installs straight from the site, runs on any device from one codebase and needs no store publishing. It is cheaper and faster, but some of the phone’s system features (camera, NFC, Bluetooth) are limited in a PWA.

• Will a SPA be indexed by search engines?

  Yes, if prerender or server-side rendering of key pages is set up. We build this in from the start and agree the scope per project so the app both ranks in search and stays fast.

• Can the app be connected to our system or 1C?

  Yes, the app works through an API — we connect it to your backend, CRM, 1C or external services. We estimate complex integrations separately after analysing the task.
