Works without signal
Every page you have opened stays readable with no data — sizes, thicknesses, weights and finishes. Useful at a site or a quarry where the bars run out.
For your phone
Keep the catalogue in your pocket
Add kotastone.co to your home screen and it behaves like an app — its own icon, no browser bar, and the catalogue keeps working when you have no signal. There is nothing to download from a store and nothing to pay.
Android — Chrome
Three taps.
- Open kotastone.co in Chrome.
- Tap the ⋮ menu at the top right.
- Tap Install app (or Add to Home screen).
If a bar offering to install appears at the bottom of the screen, just tap that instead.
iPhone — Safari
Three taps.
- Open kotastone.co in Safari.
- Tap the Share button at the bottom.
- Scroll down and tap Add to Home Screen.
It has to be Safari — Chrome on iPhone cannot add to the home screen.
What you get
Why bother installing it.
Opens like an app
Our star on your home screen, opening full-screen with no address bar in the way.
Shortcuts built in
Press and hold the icon to jump straight to a quote, the gallery, the size chart or our phone number.
Always current
It updates itself whenever you open it with signal. There is no new version to download.
Nothing to sign up for
No account, no store listing, no permissions. It is the website, kept on your phone.
Barely any space
A few megabytes. Photographs are only saved once you have actually looked at them.
No signal
Save the whole catalogue to your phone
One tap puts every page and every photograph — about 28 MB — into the app's own storage. After that the catalogue, the size tables, the weight calculator and the rates all open at a quarry, a basement or a site with no signal at all.
Saved on your own phone, not on our server. Clearing the browser's site data removes it; tap the button again to put it back.
