Since I Quit is a free Android app developed by Saad Zahoor in the Lifestyle category. This app is designed to help users quit their bad habits with ease. The app has four main screens, namely Home, Add, Extras, and Manage. The Home screen displays the time since you quit your habit and offers an achievement feature to keep you motivated. The Add screen allows you to add a custom habit or select from popular predefined habits. The Extras screen provides an option to support the developer/project and request custom features for the app. The Manage screen allows you to control your active habits by deleting or resetting them. It is important to note that the app is ad-free and allows only five habits to be added in the current update.
