Diets fail because they tell you what to eat, rather than teaching you why you eat and how to change your eating habits.


Our app uses behavioural science to retrain your mind to make healthy choices automatically, so these stick in the long run.


By building healthier habits that become second nature, losing weight feels easier and lasts longer.
