Are there any analogues of programs for iOS like "quit smoking"?

Question

iOS

I am looking for a specific program for iOS. I am sure that if I wanted to get hold of this, then someone has already invented it =)
The bottom line is the following - a countdown with a reminder for addictions. There are many analogues of such programs for quitting smoking. I want to use it for another addiction - gambling. Type: opened a program, set a reference point and started a timer. And the program will count down "days without ..." with a reminder, a la "you don't play ... days!"
