Meet your pocket coach. FittyBitty builds your plan, keeps you moving, and counts your calories from a photo. Just talk to it. A COACH THAT TALKS BACK Type or speak. "I'm in a hotel this week." "Only 20 minutes today." "I had a burrito for lunch." Your coach answers out loud, reshapes your week, and logs what you ate, your water and your weight, all from one sentence. SNAP YOUR FOOD, GET THE CALORIES Take a picture of your plate. FittyBitty estimates calories, protein, carbs and fat, and you check it before it's saved. KNOW WHAT TO ORDER ANYWHERE Snap a restaurant menu and your coach picks the three best dishes for your goal and the calories you have left, with a tip to order each one better. One tap logs it.
