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

ByteFit is a food diary with Bite, a cute green buddy who cheers every meal you log. Snap your food, pick a photo from your library or describe your meal — AI estimates calories, protein, fat and carbs and breaks the dish down into ingredients. Check the ingredients, adjust the portion and save it to your diary. AT RESTAURANTS AND STORES • Snap a restaurant menu or a delivery cart screenshot: Bite counts the macros for every dish and suggests what fits the rest of your day. • Point the camera at a barcode: nutrition comes straight from the package, you just pick the portion. BITE IS THE HEART OF BYTEFIT • Every meal you log feeds Bite: he catches the treat, chews and shows how your day has changed. • His mood reflects your day — hungry, content, full or stuffed — with no guilt and no judgement. • A fullness scale, calories left and macros at a glance. • “Bite suggests” — recipes that fit the rest of your day, from your own food and your coach chats. • Once a day Bite asks how you feel — the answer stays on your device. • Your friendship grows with the days you log, and missed days are never punished. ALSO IN BYTEFIT • AI coach: talk about your eating, ask for a recipe or set calorie and macro goals. • A diary with food photos and totals for every meal. • My food: saved dishes and recipes — no new photo or retyping needed. • Home Screen and Lock Screen widgets, and a “Cooking” Live Activity with a timer. • Gentle reminders and Calm mode, which hides the numbers. • Progress and statistics by day, week and month. Daily rhythm: steps, water and sleep next to your food. ByteFit shows steps and sleep from Apple Health, and you log water in one tap on Home, in the widget or right from a reminder. Water and sleep you log can be saved to Apple Health too. AI suggests water, steps and sleep targets together with your calories and macros, based on your answers, or you set your own. Your Apple Health data stays on your device: it is never sent to AI or to our server and is never used for ads. Without Apple Health, water and sleep still work by hand, and you can hide any tracker you don't need. Your first successful AI food analysis is free, with no account or subscription required. You can check the result, make manual changes and save it for free; the subscription offer comes later, on Home. Further food analyses, AI refinements and the AI coach require ByteFit Pro. Manual food entries, your diary, saved meals, recipes and statistics remain free, and previously saved data stays accessible after a subscription ends. Diary entries are stored on your device. AI requests are processed by our service; the privacy policy explains this processing and temporary response recovery. ByteFit Pro offers monthly and yearly subscriptions. If you have never subscribed, Bite gives you a gift after your first logged meal: ByteFit Pro at 40% off. The offer lasts an hour, is then extended to the end of the day, and the gift price also applies to renewals. Eligible customers can start an Apple three-day free trial. The App Store confirmation shows your local price and billing period. Subscriptions renew automatically unless cancelled in your Apple subscription settings. Restore purchases from the subscription screen. AI nutrition estimates may be inaccurate. Check ingredients, quantities and nutrition values before saving. ByteFit is not a medical service.
