You're on the app's own page
Put LoadOff on your phone
Installing from this page puts the app on your home screen — not a shortcut to the website. It works offline once installed.
Android: Chrome menu (⋮) → Install app.
iPhone (Safari): Share → Add to Home Screen → Add.
The name it offers should read LoadOff. If it says Thind Transport, you're on a website page — come back here and add it from this screen.
Once it's installed, open it and sign in — the app keeps you signed in after that.
