What is a PWA and how does it differ from an App?

A PWA (Progressive Web App) is a website that behaves like a native app. It can be added to your home screen, work offline, and send push notifications — but you don't need an app store to install or update it.

(1) Opens as fast as a native app; (2) full-screen mode with no browser address bar; (3) push notifications for reminders and settlement alerts; (4) certain features work offline.

How do I install on iOS and Android?

iOS Safari: open https://mrsplitter.com → tap the Share button → choose "Add to Home Screen". Android Chrome: open the same URL → tap the "Install app" prompt or choose "Add to Home screen" from the menu.

Does installing the PWA require any permissions?

No special permissions are required. Installing simply places the icon on your home screen — no personal data is accessed. The browser will ask separately when you enable notifications.
