How an app becomes a daily habit? ( In my case its very short story apps such as Wattpad & Talehunt app)

Does anyone notice this before? I was not a person who reads a lot of stories or novels. But something happened 3 months back when I downloaded the app called wattpad, on the first day i just skimmed through the app and ignored but didn't uninstall, after a week when I was just going all apps i noticed the app and started reading some stories, It was an amazing experience, I read about 4 hrs that day, story by story. after that I was reading the app almost everyday. The same thing happened with another new app called talehunt, which is very new, and very small userbase compared to wattpad, but I really liked those stories and the addiction it makes. I was not a person who likes stories, what makes me love these apps and spend my valuable time on this? Do anyone else have similar experience? How do such apps effect us?
