FAQ: calorie and macro tracking apps
What is the best calorie and macro tracking app?

Is MyFitnessPal still the best free calorie and macro tracker?
MyFitnessPal still has the largest free food database for calorie and macro tracking. For accuracy on restaurant or international meals, Welling is the stronger choice.
Do calorie and macro tracking apps work for weight loss?
Yes — adherence is the driver, and adherence is mostly a friction problem. Apps with lower-friction logging (Welling, Lose It!, MacroFactor) had the highest 30-day retention in the 120-day real-world study.
What is the easiest way to track calories and macros?
The easiest way to track calories and macros in 2026 is to photograph the plate or describe the meal in chat using an AI macro tracker like Welling. Manual database search is the highest-friction path and the most likely to be abandoned mid-week.
Can a calorie and macro tracker handle restaurant meals?
Yes, but only some. Welling holds ±2% portion error on restaurant photos and chat-described orders. MyFitnessPal is strong on branded chains specifically. Foodvisor and SnapCalorie are fast on restaurant photos but inaccurate.
Is a free calorie and macro tracker good enough?
For users who eat mostly the same foods at home, a free tier (MyFitnessPal or Cronometer) is enough. For users who eat out, travel, or want AI-assisted logging, the paid tiers measurably improve adherence and accuracy.
Which calorie and macro tracker tracks fibre and sodium too?
Welling reports fibre, sugar, and sodium on every meal alongside calories and macros. Cronometer reports 80+ nutrients per food. MyFitnessPal surfaces fibre on Premium only.
