Questions & answers
Maccy is a simple nutrition tracking app available for Android and web, and coming soon to iOS. Type what you ate in whatever terms work for you, and Maccy logs the calories and macros using USDA nutrition data.
Apps like MyFitnessPal, MacroFactor, and Cronometer all work the same way: you search a database, take a photo, or scan a barcode for every food you log. Maccy lets you type what you ate in plain language and handles the rest. Same goal, fraction of the time.
Yes. Maccy uses LLMs at 3 stages: Separating your input into individual foods, estimating portions based on your description, and picking the best nutrition-database matches. If no match is found (rare), the LLM estimates calories and macros. We have zero data retention (ZDR) and no-train policies in place with the AI provider we use, so nothing you type is ever stored or trained on by AI companies.
No. By design, Maccy has no push notifications, streaks or gamification of any kind. Maccy is your tool, and if it no longer serves your goals, it won't beg you to come back.
Maccy sources nutrition data from USDA and Open Food Facts nutrition databases, so the accuracy mainly depends on the specificity of your description. If no database match is found for an ingredient (rare), an AI estimate is used. Maccy is about as accurate as any tracker, without making you do the work.
Yes. We don't sell or share your data. We have zero data retention (ZDR) and no-train policies in place with the AI provider we use so nothing you enter is ever stored or trained on by AI companies. You can export or delete your data at any time.
No. To keep things simple there is one monthly price.
