The fast calorie tracker, built on USDA data. Say what you ate or snap a photo, and it's logged. Use Sphere free, no subscription and no card. Upgrade to Premium for photo logging, macros and more. JUST SAY WHAT YOU ATE "Two eggs, toast and a coffee." One sentence, no typing, and every food lands in your log. Voice logging is free. Start it from a Lock Screen widget or Control Center, too. FOOD DATA YOU CAN TRUST 12,000 everyday foods measured by the USDA. When a food isn't there, AI fills the gap with an estimate, and you can fix any portion in one tap: cups, ounces, grams or calories. SEARCH THAT PUTS PLAIN FOODS FIRST Everyday foods come before branded products, so the food you meant is usually the top result. MISS A DAY, KEEP YOUR STREAK Earn skip days as you log.
