Searching for an App which was posted here (App to mute audio when tilting the screen)

So just wanted to ask for an App I thought I saw here. It was one you can use to mute music, etc when you close the lid of a macbook slightly. Thought I saw it here but did not find the post about it. Was it removed or am I misremembering the subreddit? Don't find it in the thread of the banned/warned users/apps. I think it had something like tild or tilt in the name but the search doesn't help me. And if it was removed then I atleast know that I don't need to search for it or install it.
