Stop guessing. Start knowing. Your body is one of a kind. Kara combines evidence-based nutrition science with AI engineered for food, so your targets, your plan and your coaching are made for you. WHY KARA IS DIFFERENT • AI with one job: nutrition Kara's AI is not a general chatbot with a calorie label. It reads your meal in several steps and works inside a nutrition engine with safety limits that keep your calories and protein from dropping too low. • Every cuisine, recognized From sushi to pasta to a home-cooked stew, Kara's AI recognizes dishes from any cuisine, even several on one plate. Foods Kara already knows come straight from its own food database, and new dishes are reviewed and remembered, so Kara keeps getting better. • Personal to every single user Your targets and your meal plan are calculated for you alone, from your body, goal, diet style, allergies and health conditions, and they keep up as your weight changes. • Effortless Just say what you ate, snap a photo of your plate, or type the whole meal in one sentence, and confirm with a tap. A meal takes seconds to log, and your whole day only a few minutes. • A coach that knows your day Yara reads your meals, water and activity against your own targets, scores your day and tells you the next simple step. YOUR FOODS, YOUR WAY • Real-life portions: home-cooked, restaurant and packaged foods in units like a plate, spoon, glass or ladle. • My Kitchen: save the foods and combinations you eat often, with your own units and amounts, and log them again with one tap. Build packages for repeat meals like breakfast. • Smart list: Kara remembers what you usually eat at each meal and has it ready to log. A 30-DAY MEAL PLAN BUILT FOR YOU Shaped by your targets, food preferences and diet style: personalized, high-protein, keto, Mediterranean or vegetarian. Meals that clash with your allergies or health conditions are left out. Swap any meal, and when your weight or goal changes, build a new plan without losing your history. RECIPES YOU CAN COOK AND LOG Recipes with ingredients, steps, portions and nutrition per serving. Made one? Add it to your day with one tap. YOUR WHOLE DAY IN ONE PLACE Calories, macros, meals, water, weight, activity and Apple Health steps, with reminders and home screen widgets. KARA ON APPLE WATCH See today's calories, macros and steps on your wrist, and log a meal by voice or add water without taking out your phone. WEIGHT PROGRESS Every weight you log on a chart, in daily, weekly and monthly ranges, with how far you are from your goal. Add a progress photo to a weigh-in and see how you change. HOW YOUR BODY FEELS Log symptoms, feelings and energy every day, then see the patterns that showed up most during the month. TREATMENT COMPANION: A MEDICATION LOG, NOT MEDICAL ADVICE Kara does not suggest a medication, a dose or any change to your treatment. You can only log the weight loss medication and dose your doctor prescribed, record each use and set reminders on your own schedule.
