Sfira: Calorie Tracker

Most calorie apps make you hunt through a database for something that resembles what you just ate. Sfira starts with a photo. Point your camera at the plate. A vision model reads the photo and proposes what it sees: each food, an estimated portion in grams and in household terms, and the calories, protein, carbs and fat that go with it. Then it does something most calorie apps won't. It tells you how sure it is. Every item carries a confidence figure. Grilled chicken on a clean plate scores high. A sauce that might be olive oil and might be butter scores low, because the camera genuinely cannot tell. You see the doubt instead of a made-up number, so you know which figures deserve a second look. Nothing reaches your log until you tap Save. Fix a name, drag a portion and watch the macros rescale, delete something the model imagined, add the side it missed. WHAT YOU GET • Photo logging — camera or your photo library, with an optional one-line hint ("large portion", "cooked in butter") when you know something the picture doesn't show. • An estimate you can argue with — every field editable, portions that rescale the macros proportionally, confidence shown per item. • A daily view — calories against your target as a ring, protein, carbs and fat as bars, meals grouped by breakfast, lunch, dinner and snack. • Manual entry — search an offline food list, re-log something recent, enter a custom food, or quick-add bare calories. • Trends — calories against target over 7, 30 or 90 days, where your calories come from, your average intake and your logging streak. • Favorites — one tap to log a meal you eat often. • Targets that are yours — Sfira works out your BMR and TDEE from your biometrics and proposes a calorie and macro split. Every number is editable, and your edits are never overwritten. • Built for iPad — on a big screen the summary sits beside the day's meals, with keyboard shortcuts and pointer support. • Full VoiceOver and Dynamic Type support throughout. WHAT YOU NEED Photo analysis runs on your own Anthropic API key — paste it into Settings once and it is kept in your device's Keychain. You are billed by Anthropic for what you use, typically a fraction of a cent per photo, and there is no subscription to Sfira. Everything else — manual logging, targets, trends, favorites — works with no key and no connection at all. PRIVACY Your food log, your photos and your profile stay on your device. There are no accounts, no analytics and no third-party tracking of any kind. The only thing that ever leaves your phone is the meal photo you choose to analyse, sent to the model that estimates it. Delete everything at any time from Settings. HONEST ABOUT WHAT THIS IS Calorie figures are estimates. Photo estimates especially so — hidden oil, sauces and cooking methods are invisible to a camera and can move the real numbers a long way.
