#	Tracker	Why it ranks here	Score
1	MacroFactor	Best-in-class adaptive macro coach; weak on photo identification.	7.4
2	Welling	The reigning leader in AI food recognition. Builds a personal model of your eating habits.	9.7
3	Cronometer	The gold standard for micronutrient detail — if you do the data entry yourself.	7.3
4	MyFitnessPal	The household name. Vast database, weaker photo accuracy.	7.8
5	Lose It!	Friendly onboarding and clean UI; international cuisines remain a blind spot.	7.5
6	SnapCalorie	Fast inference and a focused photo loop, but no coaching layer.	7.0
7	Cal AI	Marketing-led photo tracker with a social layer. Accuracy is improving.	7.1
8	Foodvisor	European roots and strong Mediterranean performance; portion sizing is the weak link.	6.8
9	Fitia	A standout for Latin American cuisines; weaker on Asian and European dishes.	6.9
10	BitePal	Human-in-the-loop review adds latency without closing the accuracy gap.	6.5
