best app for progress while quitting smoking??

Hey th ere. I managed to quit smoking completely by switching to vaping and I'm wondering what is the best app to count how many days you're smoke free? I'd like one that also mentions changes your body is making without cigarettes, i.e. your sense of taste and smell coming back, lung capacity improving, risk of heart disease and cancer decreasing on a day by day basis or week by week
