hi,
i too am following the discover plan and have a useful app if you have a smartphone.
there is an app on itunes or android called IWatchr it is a calc which can be used for the old points or the later pro points. not only that but it also doubles up as a tracker. it allows you to add your meals throughout the day and resets for the next day. you just need to enter your food types and values to build up a menu then they are stored as you favs and you can use them over and over again. you can either go through and enter all your foods and values in one go or just add them as you use them and build up your library.
it is quite simple to use just play around with it also the developer has a website. failing that just send me a query and i will try to answer it for you. oh and the app is only 69p
hope that helps
Lee.
