My last Cigarette Timer

The app shows you all the values of an ordinary smoking cessation app. Money saved, time since last cigarette, toxins not ingested, health status, etc. What makes it different from other apps is that it helps you when you want to go back to cigarettes. It suggests you alternatives to smoking when there is a certain situation. It can be a withdrawal symptom, or a habit. The app is optimized for the Apple Watch and you can also display all data as complications (from watchOS 7) on your watch face. So you always stay up to date. You can test the app for 2 days free of charge. Good luck with your goal to become a non-smoker.
