PWA or Native App: Why IO Tech Installs Without Going Through the App Store

When people hear "app," they almost always think App Store or Google Play: search for the name, tap Install, wait for the download. IO Tech doesn't work that way — and this isn't a minor technical detail. It directly shapes how a store installs the tool and uses it day to day.

What Is a PWA?

A PWA (Progressive Web App) is a website that behaves like an app once added to a phone's home screen: its own icon, full-screen with no address bar, camera access, and offline functionality after the first load. Technically, it's still a web page — but the experience feels exactly like a native app.

Why We Made This Choice for IO Tech

Three concrete reasons drove this choice over a traditional native iOS/Android app:

• One link, two platforms. The same tool works on iPhone and Android, with no need to maintain two separate apps or go through two different review processes.
• No store review delay. An update — a fix or an improvement — is available the moment the app is next opened, with no wait for an Apple or Google review that can take several days.
• Nothing to install through a third-party account. No Apple or Google ID required for the optician setting up their store — just a link and a license key.

What This Means for the Optician, in Practice

In practice, installation takes three steps: open the link received by email, tap "Add to Home Screen" from the browser menu (Safari on iPhone, Chrome on Android), then launch the icon like any other app. Once activated with the license key, the tool works offline — useful in a store basement or a fitting area with poor network coverage.
