It would be really useful if the site could add up the daily calories over a week so if you had less on one day and more on another it would show you your weekly level rather than just treating each day separately.

in 'reports' you can view your calories for a week or month

I agree with the OP, except that I would like it to average out. So, if my daily goal is 1500 and I eat 1200 one day and 1800 the next, the weekly will show me that I met my goal of 1500 per day. Or it would work if it set a weekly goal of 10,500 and then showed me how far over or above I was.

I think the iPhone app does this. I don't have an iPhone but my friend showed me hers and if I remember it had how many cals left for the week

I can only see a bar chart when view calories over a week so have to add them all up - is there a place which adds them up for you over a week as I can't see this

It would be great if the report could say
Weekly Calorie Goal : ...
Weeks Calorie Intake: ....

And then said how much over / under your goal you are for the week (as it does for the day)

The iPad app is FANTASTIC. It shows a bar graph with the average calories consumed for the week, and it has pie graphs for the macros. I really wish the website would adopt a lot of the features from the iPad and iPhone apps.
