Simple Call Blocker is a free app for blocking unwanted calls on iOS.

It provides a basic way to block lots of numbers via a CallKit directory extension–which is great for blocking neighbor spam.

Unlike almost every other call blocker out there, mine is completely free and doesn’t need access to your contacts to work.

Try it out. It’s free.

If you want to know more, there’s a website with screenshots and a FAQ. I wrote a blog post describing my motivation for writing it, too.
