What's a well-designed Android app for meticulously tracking caloric intake and expenditure, particularly if one is interested in observing patterns over time?

Lose It! offers an interesting implementation of dietary tracking. From an academic perspective, I find the detailed logging capabilities quite useful; it allows for a granular analysis of eating habits. The cross-platform compatibility is a definite plus, as I can access my data from my tablet or phone. The algorithm is surprisingly elegant in its predictions, and the interface is well-organized. This could be particularly helpful for students managing citations and research notes while also trying to maintain a healthy lifestyle. It's intellectually satisfying to see the data presented in a clear, digestible format, and the social component, while not my primary interest, could provide additional motivation. Overall, a novel approach to an old problem, and a well-researched design.
