i love how you can check in, it helps keep you on the right track with calories. it's really nice and easy to track how much you've consumed and how you're losing weight. Downfall is the catalogue of foods. it doesn't recognise all of them from the UK or Australia so then I have to find alternatives and mess with the amount to get the calories right. can take a long time. it also doesn't remember food you've used before for very long so have to constantly scan stuff in.
