Keep a 5242 Luxury Villas Program icon on your Home Screen. This is the website, not an App Store download.
Safari uses Share → Add to Home Screen, not a website Install button. On other browsers, use their install prompt or menu steps below.
Open this website in Safari. Open Share (it may be under More), choose Add to Home Screen, turn on Open as Web App if offered, then tap Add.
Open this website in Chrome. Open the three-dot menu, choose Install and create shortcut (or Add to Home screen), then Install. Follow the on-screen steps. If only Create shortcut is offered, it may open in the browser instead.
If you opened this link inside WhatsApp or another app, first open it in Safari or Chrome. Menu names can vary by browser and version.
Internet is needed. This is still a demo: sample edits stay in this browser or installed web app, and may not carry between them. No real account, shared records, payment or offline access is activated by installation. No notifications are requested.
