iOS: When you come across a link in Safari, you usually have to copy and paste that link to use it in another app. Opener allows you to open it directly from Safari into the app of your choice.
Opener creates a share extension for Safari so when you run across a link online you can open in the correct app. For example, if you come across a Twitter link, it will open it in the Twitter app. Or if you see a Spotify playlist, it will open it up in the Spotify app.
Opener works for many apps out the gate, including Amazon, Kickstarter, Spotify, YouTube, Twitter and Overcast. It's simple, handy, and makes browsing the web a lot easier.
