How to do it

  1. Tap Share . In Safari it's at the bottom (on iOS 26, tap “•••” first); in Chrome, in the address bar.
  2. Scroll and choose “Add to Home Screen” (if it isn't there, tap “View More”).
  3. Tap “Add”. If you see “Open as Web App”, leave it on.
  4. Done: open Hortario from the new icon.

On iPhone the icon app keeps its own data: you may need to pick your area and plants again.
