Where they differ
Micronutrients
Cronometer tracks 84 micronutrients against lab-sourced data, free. For medical tracking it has no real competition.
Macros.gg tracks calories, protein, carbs, and fat. If you need vitamin and mineral data, this is the wrong app.
Staying motivated
Cronometer gives you accurate data and stays out of your way. There are no quests, parties, or shared progress.
Quests, XP, ranks, and friends who can see your progress. The data only helps if you keep logging, and this is the part that keeps people logging.
Logging speed
Entries are precise, usually weighed in grams. Gold adds photo and voice AI logging; the free tier is search and scan.
Describe the meal in a sentence and adjust if it's off. AI logging is in the one plan, uncapped.
Why people switch
Logging stops feeling like homework
Cronometer rewards precision. If weighing food to the gram wore you out, typing a sentence is the opposite.
Built-in motivation
Streaks, quests, and ranks do the job that discipline was doing.
Other people
Parties, ranked seasons, and a Discord where people post their meals. Cronometer is quiet by comparison.
Your history comes with you
Macros.gg imports your Cronometer diary, weigh-ins, and custom foods — with an undo button.
Sign in with Discord or Apple and log your first meal. Setup takes about a minute.
Get startedQuestions people actually ask
$12 a month, or $80 a year. There's one plan and everything is in it: food and weight tracking, the barcode scanner, AI logging, the nutrition assistant, full trend history, quests, XP, streaks, and the Discord. New accounts get a 3-day free trial — cancel before it ends and you're not charged.
No. Macros.gg tracks calories, protein, carbs, fat, and long-term trends. If you need micronutrient tracking for medical reasons, Cronometer is the better tool for that.
No. There's a 3-day free trial, then it's a subscription. That's deliberate: free trackers pay for themselves with ads in your food diary, upsells at every tap, or by selling your data, and we won't do any of the three. One price, no ads, nothing else sold to you inside the app.
No — this is the one competitor Macros.gg imports from directly. Your daily nutrition history, weight entries, and recreatable custom foods come across in about ten minutes, and the whole batch can be undone from Settings. See the step-by-step migration guide. Migration guide →
