Calsay — the voice-powered calorie counter and nutrition tracker that makes health logging effortless. Just speak to track your meals, workouts, and weight. No typing, no searching, no forms. Say what you ate, what exercise you did, or how much you weigh — Calsay transcribes your voice, identifies every ingredient, calculates the nutrition, and logs it all in seconds. It's the simplest calorie tracker you'll ever use. VOICE-FIRST CALORIE & MACRO TRACKING Hold the mic button and speak naturally — in any language. Say "chicken salad with olive oil and avocado" and Calsay breaks it down ingredient by ingredient with accurate calories, protein, carbs, and fat. No more scrolling through endless food databases. AUTOMATIC MEAL DIARY Every meal is organized by type — breakfast, lunch, dinner, and snacks. Your daily calorie ring and macro breakdown update in real time so you always know where you stand. Edit quantities, add items, or remove anything with a swipe. 50+ ACTIVITIES — LOGGED BY VOICE Say "I ran for 30 minutes" or "45 minutes of yoga" and Calsay calculates calories burned using MET-based formulas adjusted to your body weight and exercise intensity. Burned calories are automatically added to your daily budget. WEIGHT TRACKER WITH PROGRESS CHARTS Log your weight by just saying it. Calsay tracks every entry, plots your progress over time, and shows how your weight trend connects to your nutrition and activity — all in one place. APPLE HEALTH SYNC Calsay writes your nutrition, weight, and activity data directly to Apple Health so all your health metrics stay unified. PERSONALIZED CALORIE & MACRO GOALS Enter your age, height, weight, activity level, and goal — whether it's fat loss, maintenance, or muscle gain. Calsay calculates your ideal daily calories and macros using the Mifflin-St Jeor equation, trusted by dietitians worldwide. SMART DAILY DASHBOARD A calorie ring, macro progress bars, weekly stacked charts, logging streak counter, and BMI overview — everything you need to stay on track at a glance. Swipe between days to review your history. PAST-DATE LOGGING Forgot to log yesterday's dinner? Just say "yesterday I had spaghetti bolognese for dinner" and Calsay places it on the right date and meal slot automatically. DAILY TRACKING REMINDERS Set custom reminders for each meal — breakfast, lunch, snack, dinner, or end of day — so logging becomes a habit, not an afterthought. AVAILABLE IN ENGLISH & ESPAÑOL Full interface in both languages. Voice input works in any language you speak. Whether you're counting calories to lose weight, tracking macros for muscle gain, or simply building healthier eating habits — Calsay turns voice into data so you can focus on your goals, not on logging. One button. Your voice. Everything tracked. --- Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://calsay.app/privacy
