I certainly need something like this. Yet to be proven whether it'll work for me (though the money-back guarantee is a nice touch).
@chrismessina this is one of those few apps that I use all the time. Version 1.2.2 is buggy on Yosemite, but the app is great. (Anti-social is a good choice if you really want to lock yourself out)
I probably need this. I'm doing my daily Swift lessons, but I keep leaving Xcode to check Product Hunt :(
@erictwillis you should get The Hunt and put PH in your menubar!
