Add Worldwatch to your iPhone
Install Worldwatch on your iPhone or iPad straight from Safari, no App Store needed. It gets its own home-screen icon and opens full-screen like a native app.

Worldwatch runs as a web app, so you install it straight from your browser; there's nothing to download from the App Store. Once installed, it gets its own icon on your home screen and opens full-screen, without the Safari address bar, so it feels like any other app. You stay signed in, and it launches faster.
On iPhone and iPad you have to use Safari to install. Adding to the home screen from Chrome or another browser on iOS won't give you the full app experience.
Install from Safari
Open Worldwatch in Safari
Open Safari and go to app.worldwatch.market. Sign in as you normally would.
Tap the Share button
Tap the Share button (the square with an arrow pointing up) in the bar at the bottom of the screen. (On an iPad it's in the top-right corner.)
Tap "Add to Home Screen"
In the share sheet, scroll down and tap Add to Home Screen. If you don't see it, tap Edit Actions at the bottom and add it to the list first.
Confirm
Keep the name Worldwatch (or change it), then tap Add in the top-right. The icon appears on your home screen.
Open the app
Tap the new Worldwatch icon on your home screen. It opens full-screen, without the Safari bar, and keeps you signed in.
Turn on notifications
Once the app is on your home screen, open it and allow notifications when prompted, so you're alerted about orders and offers. You can fine-tune what you get in notification settings.
Troubleshooting
I don't see "Add to Home Screen"
Make sure you're in Safari, not Chrome or an in-app browser (for example, a link opened from your mail or messages app). Open app.worldwatch.market directly in Safari and try the Share button again.
The app opens with an address bar
That usually means a browser shortcut was saved instead of the installed app. Delete that icon and repeat the steps above from Safari. The installed version opens full-screen with no address bar.
