Zerethon Design
Install Zerethon Design
Use Zerethon Design like an app on your computer, iPhone or iPad. It opens straight to your projects, in its own window. Follow the steps for your device and browser.
You are using the installed app. The steps below stay here for your other devices.
Zerethon Design is installed. Open it from your apps, like any other app.
This browser can install Zerethon Design as an app.
On iPhone and iPad there is no Install button: in Safari, tap Share, then Add to Home Screen. The steps are below.
Not installed. You can install it later from the browser’s menu.
This browser has not offered to install the app on this page. Follow the steps for your device below.
Choose your device
Mac
Installing adds Zerethon Design to your Applications, Launchpad and Spotlight. It opens in its own window, without tabs or an address bar.
Chrome or Edge
- Open design.zerethon.com in Chrome or Microsoft Edge.
- Click the install icon at the right end of the address bar (a screen with an arrow). If it is not there: in Chrome, open the ⋮ menu → Cast, save, and share → Install page as app…; in Edge, open the ⋯ menu → Apps → Install Zerethon Design.
- Click Install.
- The app opens in its own window. Later, open it from Spotlight (⌘ Space, type “Zerethon Design”), Launchpad or the Applications folder. To keep it in the Dock, right-click its Dock icon → Options → Keep in Dock.
Safari
Safari 17 or later (macOS Sonoma or later) can add a website to the Dock. It works differently from Chrome: there is no install icon in the address bar.
- Open design.zerethon.com in Safari.
- Choose File → Add to Dock… (or click the Share button → Add to Dock).
- Keep the name “Zerethon Design” and click Add.
- Open it from the Dock, Launchpad or Spotlight.
Older Safari versions cannot add websites to the Dock — use Chrome or Edge instead.
Windows
Installing adds Zerethon Design to the Start menu. It opens in its own window with its own taskbar icon.
Chrome or Edge
- Open design.zerethon.com in Chrome or Microsoft Edge.
- Click the install icon at the right end of the address bar (Edge shows “App available”).
- Click Install. Edge then offers to pin the app to the taskbar or Start, or to create a desktop shortcut — choose what you like.
- Later, open it from the Start menu (type “Zerethon Design”). To pin it, right-click its taskbar icon while it is open → Pin to taskbar.
No install icon? Use the browser menu instead: in Chrome, ⋮ → Cast, save, and share → Install page as app…; in Edge, ⋯ → Apps → Install Zerethon Design. Menu names can differ slightly between browser versions.
Linux
Chromium-based browsers — Chrome, Chromium, Edge, Brave, Vivaldi — can install Zerethon Design. Where the app then appears (app menu, launcher, dock) depends on your desktop environment, so the last step can look different on your system.
- Open design.zerethon.com in your browser.
- Click the install icon at the right end of the address bar, or use the browser menu: in Chrome, ⋮ → Cast, save, and share → Install page as app….
- Click Install.
- Look for “Zerethon Design” in your desktop’s app menu or launcher.
If the app does not appear in your app menu — this can happen with browsers installed as Snap or Flatpak packages — open it from the browser instead: chrome://apps in Chrome, edge://apps in Edge.
Firefox on Linux does not install websites as apps.
iPhone
On iPhone there is no install button. You add Zerethon Design to your Home Screen from Safari’s Share menu. It is not an App Store app and there is nothing to download from the App Store.
- Open design.zerethon.com in Safari.
- Tap the Share button (a square with an arrow pointing up). On iOS 26 it can be inside the ⋯ button next to the address bar.
- Scroll down the list and tap Add to Home Screen. If you see Open as Web App, leave it on.
- Keep the name “Zerethon Design” and tap Add.
- Go to your Home Screen and tap the new Zerethon Design icon. It opens full screen, without Safari’s address bar.
Since iOS 16.4, Chrome, Edge and Firefox on iPhone can also add a website to the Home Screen from their Share menu. Safari is the most direct way.
iPad
On iPad you also add Zerethon Design to your Home Screen from Safari — the Share button is in a different place than on iPhone.
- Open design.zerethon.com in Safari.
- Tap the Share button at the top right, next to the address bar. On iPadOS 26 it can be inside the ⋯ button.
- Tap Add to Home Screen (scroll down the list if you do not see it). If you see Open as Web App, leave it on.
- Keep the name “Zerethon Design” and tap Add.
- Tap the new icon on your Home Screen. Zerethon Design fills the screen without Safari’s toolbars.
Safari or the Home Screen app? Both open the same Zerethon Design. The Home Screen app is not shared with Safari: it keeps its own sign-in, so sign in once more there. Your projects are in your account, so they are the same in both.
Which browsers can install it
| Device | Browser | How |
|---|---|---|
| Mac | Chrome, Edge | Install icon or browser menu |
| Mac | Safari 17 or later (macOS Sonoma or later) | File → Add to Dock |
| Windows | Chrome, Edge | Install icon or browser menu |
| Linux | Chrome, Chromium, Edge and other Chromium browsers | Install icon or browser menu |
| iPhone | Safari (also Chrome, Edge, Firefox on iOS 16.4 or later) | Share → Add to Home Screen |
| iPad | Safari (also Chrome, Edge, Firefox on iPadOS 16.4 or later) | Share → Add to Home Screen |
| Android | Chrome, Edge, Samsung Internet | Install prompt or menu → Install app / Add to Home screen |
Firefox on Mac and Linux does not install websites as apps. You can always use Zerethon Design in any modern browser tab without installing it.
What installing changes — and what it does not
- It is the same Zerethon Design. The app is the website in its own window: same features, same account, always the latest version. There is nothing to update by hand.
- It opens to your projects. The app starts on My projects; if you are not signed in, it asks you to sign in with your Zerethon account first.
- It needs an internet connection. Without one, the app shows a “You are offline” page. Samples, the layout library, your projects, plans, the 3D view and signing in all need the connection.
- Your projects live in your account, so they are the same in the app, in the browser and on your other devices. Installing does not copy them to your device.
Troubleshooting
There is no install icon or “Install” menu item
- Make sure the address is design.zerethon.com and the page has finished loading. Reload once.
- Use a normal window, not a private or incognito one.
- If you opened the link inside another app (a chat or social media app), open it in Chrome, Edge or Safari itself.
- It may already be installed: the browser then offers Open in Zerethon Design instead. Look for it in your apps.
- Update your browser to its latest version.
“Add to Home Screen” is missing on iPhone or iPad
- Scroll down to the bottom of the Share menu. If it is still missing, tap Edit Actions at the bottom and add it.
- Use Safari, or update to iOS / iPadOS 16.4 or later to use another browser.
- Screen Time or a device managed by a school or company can block adding websites to the Home Screen. Ask the person who manages the device.
Removing the app
- Chrome or Edge: in the app window, open the ⋮ or ⋯ menu → Uninstall Zerethon Design.
- Safari on Mac: delete Zerethon Design from your Applications folder.
- iPhone and iPad: touch and hold the icon → Remove App.
Removing the app does not delete your account or your projects.
