The Wean Machine app enables a smoker to set easily achievable targets to enable them to gradually reduce their cigarette consumption over six weeks in conjunction with using NicoBloc to either significantly cut down or to stop altogether.

The reduction targets are based upon the experience of many smokers who have used this programme. The plan is flexible in that the next week's suggestion is based on what actually happened in the previous week rather than the previous week's plan as sometimes unpredictable things happen in smoker's lives that can either speed up or slow down their progress.
