Is Cronometer a good food tracking app? Full 2026 review, accuracy, pricing and alternatives
The gold standard for micronutrient detail — if you do the data entry yourself.
Our verdict: should you use Cronometer to track your food?
Cronometer is a competent tracker with a clear identity, but it sits firmly in the field of "good enough for casual use." In our benchmark it identified 63.1% of dishes correctly and missed portion sizes by ±19.1% on average — figures that make daily macro accuracy a coin flip on mixed plates.
If you are deciding between Cronometer and our overall winner, the practical question is whether the ecosystem advantages outweigh giving up roughly a 18-point portion-error gap versus Welling.
