Daily Deeds sits somewhere between a to-do list and a quantified self app. You list certain tasks or activities that you would like to get into the habit of doing (going for a jog, cleaning the house, buying the milk etc.), and then it allows you to track how well you’ve done at seeing them through. Filling up the empty boxes with a tick is extremely satisfying, but it’s easy to fall into the trap of being over-ambitious. You can also turn your progress into a PDF report to share with friends.
