Apple has posted a short tip on how to share the iPad and iPhone apps you like right from the iTunes App Store page. If you click or tap an App Store link here at TiPb, or are simply browsing and come across something you know will interest a friend or special someone, it's great to be able to send it them via email. Here's how.
Whether you shop on your computer, iPhone, iPad, or iPod touch, you can use Tell a Friend and Gift This App to share your enthusiasm with friends. On an app's page in the App Store on the computer, click the downward pointing triangle next to the Buy App or Free App button to see the options--Tell a Friend, which lets you send an email link, and Gift this App, which lets you buy the app for someone else. On the iPhone and iPod touch, scroll down to the bottom of an app's page to find the buttons for those options. On the iPad, use the links on the upper right of an app's page. In all cases, you'll be asked to sign in with your Apple ID if you haven't already, before you complete your intended action.
There you go, that's it! If you have any other cool ways to share your apps, let me know!
