Best macro tracker for endurance athletes
For endurance work, the metrics that decide a session are carb periodisation, sodium, and timing — not lifetime totals.
How we judged this category
Cronometer wins on data fidelity for the metrics that matter to endurance: carb timing, sodium, magnesium, and iron. Welling is the easier daily driver; pair the two for race weeks.

Other categories you may want
Muscle gain / lean bulk
A lean bulk requires hitting a small daily calorie surplus and a protein floor — every day, with low variance.
Cutting (bodybuilding)
On a contest prep or aggressive cut, the price of underestimating a portion is real — by stage day, a 5% portion error compounds into kilos of mis-tracked food.
Micronutrients
If you are tracking iron, B12, magnesium, omega-3, or vitamin D, the tracker is now a database problem more than a vision problem.
