content: Pretty good so far. Blocks me from not using any other distracting app and its like playing a game that rewards you for stuying working or whatever you are doing. Ive only used it for a a few hours and havent gotten many adds with the free version so thats a plus. The only thing I wish they could add although I dont know if this would be possible is to allow whatsapptelegram conversations with certain people because when studying I tend to ask questions to friends.
