Macrion is a fast, private macro and calorie tracker for people who just want to hit their numbers — without handing over their data.

Everything you log lives on your device. There's no account to create, no sign-in, no ads, and no tracking. Your weight, your goals, and your food diary are yours alone.

LOG FOOD IN SECONDS • Scan a barcode to pull nutrition facts from the Open Food Facts database • Search whole foods, everyday meals, and name brands from USDA FoodData Central • Log by grams or by servings — Macrion does the math

KNOW YOUR TARGETS • Built-in macro calculator estimates your daily calories from your age, height, weight, activity level, and goal • Splits your calories into protein, carbs, and fat automatically • Adjust any target by hand whenever you want

STAY ON TRACK • See your daily calories and macros at a glance • Review your history and daily logs • Simple, distraction-free design

PRIVATE BY DESIGN • No account and no login • Your data never leaves your device • No analytics, no advertising, no third-party tracking • Food searches send only your search term or barcode to the nutrition databases — nothing personal
