I'm also a mySugr fan, found it massively helpful as it's an app that makes me want to use it. I paid to upgrade it to the Pro version after winning a trial and so glad I did, as that gives you the search function meaning you can search through previous meals, it takes you to that day and you can see what happened. As I cook nearly all my meals from scratch working out the carbs can become quite involved. At least now when I get it wrong I can learn for next time!
