WeighIn is the fun and easy way to keep track of your calories and chart your weight-loss progress.

Set a daily goal and then record the number of calories you have consumed during meals and the number of calories you have burned through exercise. You can then see at a glance your daily totals and how many calories you have "saved".

Each entry lets you define the type of meal or exercise, the number of calories consumed or burned along with a brief description (or excuse!).

Chart your weight-loss by entering your weight at regular intervals and reviewing the weight graph.

Choose between kilograms or pounds and calories or units (for unit based weight loss programs).

Now you don't have to carry around a little notebook or simply remember what you ate - it's all there on your iPhone/iPod.
