Both MPAZI App (the ERP) and Core Market (the marketplace) can be installed directly from your browser, on a phone or a computer.
Visit MPAZI App or Core Market in Chrome, Edge, or Safari, while logged in.
On mobile, it's in the menu/sidebar; on desktop, most browsers show an install icon in the address bar. Tap or click it.
Your browser will ask to confirm - accept, and an icon is added to your home screen or desktop, just like any other app.
From then on, launch it from that icon - it opens in its own window without browser tabs or address bars, and keeps working even on a shaky connection.
