I haven’t personally upgraded but I remember looking in the community forum for something and saw a complaint message from someone who had upgraded and didn’t think it was worth the money.

Hey there – I’m not premium, but one of the annoying things about MFP is that it will give you a stern warning message when you try and “Complete Entry” on less than 1,000 Calories! Its slightly annoying but otherwise a good app for calorie counting and has most foods. Good luck.
