1) Search found all the ingredients I needed or pretty close approximations which was cool. Multiple units of measurement was an excellent choice. Food data looks USA - it would be helpful to know that as a UK user.
2) I had to make a username and password which will put off some potential users. Why not make it log in with Facebook/Google as an option?
3) I entered a quantity of tortillas and couldn't amend it without deleting the item. Was I doing something wrong?
4) As an active 6'2" man I suspect I need more calories than average. How about activity level/height/weight options? Kudos for having 'pregnant' and 'Breastfeeding' as options. However they would be more powerful as flags - my wife is both pregnant and breastfeeding! Or even 'add person' so one can look at nutritional info for cooking for a family.
I'm interested to see how this tool evolves! Good work!
