Agree that keeping lists is very useful for exposing what you're doing to others (and it improves productivity!). Disagree in this case with making these lists digital and giving your cofounder the ability to add entries because it encourages micromanagement and it sounds like your cofounder is rubbing you the wrong way with that already. What I've seen work is short daily meetings of 5-10 minutes where people update each other on what they are doing. You can bring your notebook and he can bring his. Neither of you should have the spare time to micromanage the other. Keep him busy, and keep yourself busy too.
