Quick picks: MacroChat for natural-language logging • Cal AI / MFP for photo + database scale • MacroFactor for adaptive coaching • Cronometer for micronutrient precision • FatSecret for a generous free tier

1. MacroChat — best for natural-language food logging
MacroChat is an AI calorie tracker built around a simple idea: say what you ate. Users describe meals in plain language and get estimated calories plus protein, carbs, and fat — without scrolling a giant database for every entry.
Choose MacroChat if: you want the fastest text-based workflow, macro summaries, and an independent app outside the MyFitnessPal ecosystem. See Cal AI alternative comparison.
2. Cal AI — best for photo-only speed (now MFP-owned)
Cal AI popularized snap-a-photo calorie logging. MyFitnessPal acquired Cal AI in March 2026, combining viral AI photo entry with MFP's database scale. It remains a top pick for users who eat mostly plated meals and want instant photo estimates.
Choose Cal AI if: photo logging is your primary workflow and you are comfortable inside the MFP ecosystem. Read the acquisition context.
3. MyFitnessPal — best for database breadth
MyFitnessPal still has one of the largest nutrition databases and deep integrations. The 2026 Today tab redesign frustrated longtime users, but it remains a default choice for barcode-heavy eaters.
Choose MyFitnessPal if: packaged foods and database search matter more than logging speed. Read about the 2026 redesign backlash.
4. MacroFactor — best for algorithm-driven coaching
MacroFactor targets users who want adaptive calorie and macro targets based on trend data — less about AI photos, more about structured coaching logic.
5. Cronometer — best for nutrient depth
Cronometer appeals to users who care about micronutrients and verified database sources. Logging is more manual but analytically deep.
6. FatSecret — best free calorie tracker for budget users
FatSecret frequently appears in "best free calorie tracking app" searches because of its usable free tier and community features. Tradeoff: less AI-native than newer apps.
