Zee

Read full description

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.

About

LeanFast

Read full description

Plan, track and keep up your intermittent fasting, with water, weight and food in one place. LeanFast shapes a plan around your body and your week, shows Fasting or Eating at a glance, logs your fasts, water, meals and weigh-ins, and suggests recipes for your eating window. No ads, no trackers, AI that stays on your device, and safety built in. Free to start. WHY LEANFAST • No ads, ever. No trackers, and your data is never sold. • Private AI: with Apple Intelligence, Coach answers your questions on your device, with the sources behind each answer, and Lens reads labels and barcodes there too. Smart Lens is optional, runs in Europe and doesn't keep your photo. • Safety first: a short health check adapts your plan, and "I don't feel well" stops your fast and calls the local emergency number in 234 countries and territories. • Backed by science: every source is listed in Settings › Health sources. • Accessible: VoiceOver, Dynamic Type at every size and Reduce Motion. • Everywhere: iPhone, iPhone Duo, iPad and Apple Watch. ALWAYS OBVIOUS One big word tells you where you are: Fasting, Eating or Not fasting, on Today, your Lock Screen, widgets and Apple Watch. Tap Start fast in the evening reminder, or turn on Autopilot: every planned fast starts when your eating window closes and ends when the next one opens. PLANS AS UNIQUE AS YOU LeanFast recommends Spark (from 12:12), Flow (the classic 16:8) or Blaze (longer fasts) and eases you in over four weeks. Shape every day on a 24-hour dial: brunch on Sunday, a late dinner on Friday, rest days when you need them. A TIMER YOU CAN GLANCE AT Follow your body stage by stage, with a new explanation at each milestone, on your Lock Screen, in the Dynamic Island, widgets and Control Center. Siri can start your fast, and the Watch app keeps going when your iPhone is out of range. MOTIVATION THAT'S GOOD FOR YOU Weekly challenges and levels reward consistency, water and logging, never longer fasts. A sick day never breaks your streak, and friendly water reminders let you log a glass from the notification. LEANFAST PRISM • Lens: a Fast-Friendly grade, nutrition facts and healthier swaps for any meal, label or barcode. • Kitchen: 96 photographed recipes to break your fast, with cook mode, timers and a shopping list. • Coach: a weekly review, answers to your questions and a nudge when your plan should change. • Deep insights: weight trend, goal forecast, consistency calendar and time in each stage. • Ring themes, app icons, progress photos, Streak Shields and custom fasts. WORKS WITH APPLE HEALTH Fill in your profile from Apple Health, import weigh-ins from your smart scale and save the weight and water you log. You choose what's shared. PRICING Free to use, no account needed. Prism is available monthly or yearly (each with a 7-day free trial) or as a one-time lifetime purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period; manage them in your Apple Account settings.
