Don't lose time every day to check who liked your posts! Just open the list and run it. FREE & NO spam, NO ads, NO registration.
Very simple app with timeouts between clicks. Will be updated if FB changes something. But I suggest you to try pro version, it automatically scans all posts, so if someone likes your old post - you catch him!
With pro version you save a lot of time and you have 10-Day Money-Back guarantee and a possibility to cancel the order in first 30 minutes automatically. So why not try it?

Is it LEGAL?
Yes, script doesn’t violate any fb rule, also it was approved by fb in May 2017 when they asked us to remove some nice features :(
But any website has limitations, do not spam comments with links or comments that can be reported by people. Use responsible!
