Common questions
What is a PWA and how does it differ from a native app?
A PWA runs on modern web technology but behaves like a native app. Users add it to their home screen in one tap, get full-screen layouts and push notifications — without downloading through the App Store or Play Store.
Do we need to pay annual Apple or Google developer fees?
No. Because PWAs install directly via the browser, you bypass store approval delays, annual developer fees and app-store commission cuts.
Can you build secure client portals where customers log in?
Yes. Using Supabase enterprise-grade authentication, we build secure portals where clients log in to view job updates, access documents and manage account details.
How long does a custom web app or portal take?
Most PWAs and custom client portals are designed, engineered and live within four to six weeks.
