I think software (or a service) won't be the solution to your problem. I know some people are trying to solve this with gamification or accountability apps, but in my experience those only work short-term because they don't address the core issues responsible for the lack of motivation, although I'm sure they help establish good habits in some cases. Lack of motivation usually stems from a lack of energy, which can stem from both physiological as well as psychological issues, which can stem from spiritual issues (the sense of self and how it relates to your environment). If I'm well rested and in harmony with my authentic self, I usually don't have a problem finding the motivation to do things that are good for me.
