Sharing and action extensions, both part of Apple's Extensibility feature in iOS 8, make it easier than ever to get things done on iPhone and iPad. No longer do you have to switch to an app just to upload a photo to Pinterest or save an article to Instapaper, or hunt down 1Password or Bing just to copy a password or translate a web site. Now all that functionality comes to you, where ever you are, at the tap of the Share button. And these are the best iPhone apps implementing them.

Pinterest

Finding and sharing pins prior to iOS 8 wasn't all that much fun. You needed to copy the link to your clipboard and then go back into the Pinterest app and paste it back out. Now, whenever you want to pin something, you can do it right then and there simply by bringing up the share sheet and tapping the Pinterest button.

Read-it-later services used to have to resort to complex JavaScript bookmarklets or hope for third-party integration to try and make links easier to move articles and links from your iPhone and into their service. Now, thanks to sharing extensions, almost anything can go from your phone to your Pocket in just two taps. Free - Download Now Instapaper

Find an article you like on the web and want to save it to read later? Don't worry about copying the link, jumping over to another app, and hoping it detects the link in the clipboard and offers to add it. Just tap the share button and the Instagram button, and let iOS 8 do all the work. Free with IAP - Download Now 1Password

Back in the dark days before iOS 8, if you want to get your login out of 1Password and into another app, you had to switch between the two and use copy and paste to get you through. Now, whether you're in Safari or any other app, all you need to do is bring up the share sheet, tap the action extension, authenticate with Touch ID or passcode, and your passwords get autofilled. It's not magic, but it's close. Free with IAP - Download Now Transmit
