Snap a meal. Watch it burn off. Zee is an AI calorie tracker with a twist: every meal you log gets a live clock. See how long your body is likely still working through it, when your burn window opens, and how your whole day adds up in a calorie bank that forgives a big dinner. LOGGED IN SECONDS • Snap a photo. Zee splits the plate into items with calories and macros • Or just say it: "chicken, rice and half an avocado" • Barcode scan, saved meals, and one tap for "same as yesterday" • Fix anything in plain words: "the rice was half that" A LIVE CLOCK FOR EVERY MEAL • Digesting, then burning: one thick ring you read at a glance • A heads-up when your last meal is likely digested A CALORIE BANK, NOT A DAILY LIMIT • Your deficit adds up across the day, so one big meal is a withdrawal, not a failure • Protein target tracked all day • Streaks with saves, a morning recap and a weekly report YOUR PLAN, WITH A DATE • Answer a few questions and see the day you're likely to reach your goal weight • Smart reminders at the times you usually eat, quiet while you sleep ZEE, YOUR AI COACH • Ask what to eat next.
