Most calorie trackers just log what you eat. MacrosGPT coaches what you do about it. Meet Mac, your AI personal fitness coach who happens to live in your phone. He tracks both calories and workouts for you in seconds. Snap a picture or just text what you ate, and he logs it instantly. Then he does what a food diary can't: he checks every week and tells you if you're on track, or what you need to change. Told Mac you're "very active" during setup but only log one workout a week? He sees that. He'll call it out. That's the difference between a food diary and a coach. HOW MAC COACHES - Tell Mac your goals, body, and lifestyle. He sets your exact personalized macros and adjusts as you progress. - Mac watches your patterns across meals, workouts, and weigh-ins. Miss protein three days straight? He'll say something. Stalling for 3 weeks? He investigates why, and suggests a plan change you approve with one tap. LOG FOOD EASILY - Text it or speak it: "2 eggs, toast and a latte." Mac logs it instantly. - Snap a photo. If the photo isn't clear, Mac asks instead of guessing, so your data stays accurate. - Scan a barcode, search the food database, or add calories by hand. Tell Siri, or log from your Apple Watch. YOUR WORKOUTS COUNT TOO - Track gym sessions, runs, walks, hikes, anything you want, with accurate calorie burn based on your body profile. Mac measures your real activity, not your guess. MAC REMEMBERS AND REMINDS - Tell Mac what matters to you, like allergies, foods you love or a late work schedule, and he remembers it. - He keeps your personal bests and checks whether his suggestions stuck. - Timers and reminders: "remind me to drink protein in an hour" and he pings you. WHAT CHANGES WHEN YOU HAVE MAC - You stop guessing if your plan is working, Mac shows you the math. - You stop forgetting what works, your patterns and preferences are saved. - You stop stalling without knowing why, Mac catches plateaus before you even notice. - You stop logging food into a silent journal, Mac responds instantly with real coaching based on your own data. - You stop choosing between tracking food and tracking workouts. Mac does both! INCLUDED - Syncs with Apple Watch and Apple Health. - Daily meal plans built around your macros, with weekly grocery lists. - Preferences built in: keto, carnivore, vegetarian, vegan, pescatarian. - GLP-1 mode: dose reminders, and coaching around low appetite. - Mac speaks 22 languages!

Lighter is the simplest way to track what you eat. Open the app. Type what you ate. That's it. No forms. No dropdowns. No food databases to search through. Lighter uses AI to understand natural language — type "coffee and a bagel" or "grande oat milk latte from Starbucks" and get an instant calorie estimate. WHY LIGHTER IS DIFFERENT Most calorie trackers feel like spreadsheets. Lighter feels like a notes app that happens to know nutrition math. There's no learning curve. There's nothing to set up. You open it, you type, and your day is logged. The name reflects the experience: a lighter way to log meals. No heavy interface. No clutter. Just a quiet daily total and the freedom to type in your own words. KEY FEATURES • Natural-language logging — describe meals in your own words • AI-powered calorie estimates using live web search and language understanding • Personalized daily calorie target based on your stats and activity level • Live preview as you type — see calories before you save • Tap any entry to edit, swipe to delete • All your data stays on your device DESIGNED TO STAY OUT OF YOUR WAY Lighter was built around one idea: tracking food shouldn't feel like work. The interface is a single canvas with a cursor. No tabs, no charts, no notifications. Just you, what you ate, and a quiet daily total. PRIVATE BY DESIGN No accounts. No sign-up. No email required. Your entries are stored locally on your device. We never see your food log.
