The editorial team
Who researches and reviews the calorie tracker apps?
Every ranking on The Calorie Guardian is produced by a named expert and checked by a second. Our team pairs nutrition science and clinical practice with data engineering, coaching, and usability research, so each of the 10 scoring criteria is owned by someone qualified to judge it.
