Useful signs of progress include whether you had the selected meal, whether the snack was ready at the right time, whether you felt comfortably fed, and whether you could resume after a disrupted day.
Use the progress tools available in your app and keep brief notes if helpful. Look for a pattern you can improve: a reminder that arrives too late, a preparation you avoid or a regular meal that leaves you hungry.
Weight is one part of the review. The aim is to learn what makes the routine repeatable, without treating a missed entry as a failed day.
