- More a coaching program than a precise tracker
Our verdict on Noom
Noom is a coaching program with tracking attached rather than a precision tracker. Its psychology and accountability are genuinely strong, but it is costly and not the most accurate way to count calories. For accurate, low-cost tracking with coaching, Welling AI is the better value.
