Miriel AI vs MyFitnessPal

Built for children, not adults scaled down.

MyFitnessPal is a strong adult calorie tracker. For its intended job, it is hard to argue with. For pediatric nutrition specifically, it was not designed to do what Miriel does. Here is a direct comparison.

When MyFitnessPal fits

MyFitnessPal is the dominant calorie-tracking app for adults. If you are an adult tracking your own intake, it is still a strong choice — its food database is enormous and its weight-loss community is mature.

Why it falls short for children

  • — Recommends adult portion sizes by default, even when a child's profile is created.
  • — No per-child allergen alerts; allergens have to be filtered manually by the user.
  • — No age-appropriate texture or choking-hazard warnings — a 2-year-old is treated identically to an adult.
  • — No growth percentile context. Recommendations are around adult weight goals, not pediatric growth.
  • — No support for sibling profiles with different needs eating from the same meal.

When to pick which

If you are an adult tracking your own calories, MyFitnessPal is still excellent. If you are a parent planning your child's nutrition with attention to growth, allergens, age-appropriate portions, and pediatric clinical guidance, MyFitnessPal is not the tool. Miriel was built specifically for the second job.
