Lose weight without giving up the foods you love
Build a sustainable logging habit, understand your eating, and reach your goals — without forbidden foods or strict rules.
Consistent food diary use is the single best predictor of weight loss success — better than the diet you choose.

So what makes a diary actually stick?
Making it effortless to log — every single time.
Log your meal in under 10 seconds — with a photo or your voice
No searching, typing, or guessing portion sizes. Just point and shoot, or say what you ate. Because the harder logging is, the less often people do it — and logging frequency is what actually predicts success.
Built around your real life
Once logging is effortless, the rest of the program can actually work.
A program that builds with you
Start with just the logging habit. Everything else follows naturally.
