Carma helps you keep track of your daily activities. It is similar to other apps but has one significant difference, which enables many new capabilities.
With Carma you can score each type of activity depending on its helpfulness. Just decide how many imaginary points you will get for finishing an activity. This gives you the ability to compare days even if you did completely different things during them.
Another interesting feature is that you can share your daily progress with friends. They will only see your progress and will not know what specific actions you do. The sharing feature is implemented using iCloud, so it is secure and no information is accessible for me, the developer.
