A few months ago, something tragic happened. I lost my mini notebook filled with my lists (list for planning a part, work list, home project list, etc.) I also had new book ideas listed in the notebook. I searched everywhere and the notebook was never found. This app for smart phones makes it so I can have my lists in a safe place. Now what I am doing is checking my app for things I need to do and making a daily list on this little clipboard I carry around. It works out wonderfully. Check the app out here.
