Smoking Ninja is a free Android application designed to help users track and manage their smoking habits. The app allows users to manually log the number of cigarettes smoked each day, providing a straightforward way to monitor smoking behavior. Users can visualize their smoking activity over time through easy-to-read charts, enabling them to identify patterns and trends in their habits. This approach encourages users to understand their daily smoking behavior better and work towards reducing or quitting smoking at their own pace.

With features that support habit change, Smoking Ninja allows users to set personal goals aimed at reducing cigarette consumption. Users can track their daily and weekly progress, which helps maintain motivation over time. Importantly, the app prioritizes user privacy, ensuring that all data is stored locally on the device without any collection or transmission to external servers. It is important to note that the app is intended for lifestyle tracking and is not a substitute for professional medical advice.
