Frequently Asked Questions
Best calorie tracker with free barcode scanner?
MyFitnessPal — free unlimited barcode scanning with the largest database and highest hit rate. Nutrola, Cronometer, and Lose It also include free barcode scanning on their free tiers.
Does Nutrola have a free barcode scanner?
Yes — Nutrola's free tier includes unlimited barcode scanning with verified database entries. The barcode feature is separate from the 3-scans-per-day AI photo limit.
Why does MyFitnessPal have a larger barcode database?
MyFitnessPal allows user-submitted barcode entries, which scales the database faster but introduces inconsistent macro data. Verified-database trackers (Nutrola, Cronometer) have smaller barcode databases but cleaner data per entry.
Best barcode scanner for European groceries?
Yazio — strongest European grocery brand coverage. MyFitnessPal also covers Europe well but Yazio's German, French, Italian, and Scandinavian product coverage is deeper.
Should I use barcode or photo-AI for packaged foods?
Barcode for packaged foods (more accurate, faster). Photo-AI for restaurant or homemade meals (no barcode available). Nutrola supports both — barcode for packaged, photo-AI for cooked.
How accurate are barcode-matched calorie entries?
Verified database entries (Cronometer, Nutrola) match the package label exactly. User-submitted entries (MyFitnessPal, FatSecret) sometimes have macro errors of 5-15% relative to the label.
