Wow, that's crazy. I actually USED DailyBurn at one point and I didn't even know this existed. Their strategy of separating everything into a bunch of superfluous apps seems to have failed pretty hard in this instance (they have a barcode reading calorie tracking app separate from their food entering calorie tracking app with neither as a superset of functionality, even though these should clearly be a single app if you want a good user experience).
Apparently the quality of the estimates is very poor for the app. The problem is that DailyBurn LITERALLY uses Mechanical Turk[1], which I don't think is what you would need to do to get accurate estimates. You would have to actually have in-house talent with training and feedback on estimating the size and calories of food. I'm pretty good at estimating the calorie content of common foods just by eyeballing because I've done it for a long time and know generally what goes into them, but this is obviously an acquired skill.
