Block Distracting Websites on your iPhone

Inspired by a well known SelfControl, it aims to provide a similar functionality on iOS. This app allows you to temporarily block distracting websites on Safari browser. You can unlock them again but it requires that you think twice before doing so: "Do I really need to browse funny cat pictures right now?". Optionally you can set a timer, not allowing you to unblock distracting websites until the time is up.
