Aim training game 10 euro?

I wanted to ask if anyone of you knows what the Aim Training Game with the orange blocks is called, among other things also used by some fortnite streamers like tfue to practice aim. I think it costs about 10 euro, if someone of you with this information could help me I would be very grateful
