The iOS app runs in the background and opens websites when you send them to your mobile device from the Chrome extension. Just make sure to say "Yes" to recieving Push Notifications.
The Chrome extension can send any website to your mobile device. If you have the website's app installed (like Yelp, Rdio, or Instagram), it will open in that app! You can also send phone numbers and links to App Store downloads.
Let your friends know what you're using Push Mobile for! From sending Yelp listings to your phone before you leave the office to installing new apps mentioned on Tech Crunch, Push Mobile can enhance your mobile life!
