This is just great!! I saw my favorite youtuber using this and I was like what the hell is she using that enables you so much facilities like you are bound6to stay focused. I literally searched for the name of this app and I finally found it. I am using it for 1 month now and it's the best..!!! ❤ but sometimes it just don't notifies me when the time is over and sometimes just keeps counting the time even when I m watching YouTube or instagram on my phone.
