Log what you eat by search, voice, barcode or photo. Mamey Planner calculates your calorie and macro target based on your goal, and helps you stick with it — free, no ads, no artificial limits.
The mamey — also called zapote (Pouteria sapota) — is a tropical fruit native to Mesoamerica: rough brown skin, a dense, generous salmon-orange flesh, with a flavor somewhere between sweet potato, honey and almond. It's been grown and eaten in Mexico since long before the Spanish arrived.
In colloquial Mexican Spanish, "mamey" is also slang for someone muscular, strong, built — a physique that's as generous as the fruit's own flesh. "Está bien mamey ese cuate" is a common, affectionate way of saying someone's jacked.
That's where the app's name comes from: a character that literally starts as a pit and, with consistency, becomes mamey. That's why the mascot grows with you — it's not just a cute metaphor, it's the actual joke behind the name.
