Take a photo. That's the whole app. No account. No onboarding. No setup screen asking your goals before it'll do anything. You open ZiB, you photograph your food, and it's logged. FREE. NOT "FREE." No paywall. No subscription. No locked features, no trial that expires, no upsell after your third meal. If you want to help with the running costs there's a tip jar in settings, and it unlocks absolutely nothing. SIMPLE ON PURPOSE One screen. Your meals, and a camera button. That's it. - No streaks - No badges - No notifications telling you that you've broken anything - A day you didn't log is just a day you didn't log HOW IT WORKS Photograph your meal. ZiB works out what it is and how much of it, then pulls the calories and macros from the USDA nutrition database — real published numbers, not invented ones. If it's wrong, tap it and fix it. It remembers, and gets better at the food you actually eat. PACKAGED FOOD Scan the barcode for that product's exact label. If the nutrition panel is visible in your photo, ZiB just reads it. APPLE HEALTH Optional and off by default. One-way: ZiB writes your meals to Health and reads nothing back. PRIVATE No account, no sign-up, no analytics, no ads, nothing sold. Your meals stay on your phone. THIS IS HALF THE PRODUCT The other half is a screenless wristband. It notices you've started eating, buzzes once, and logs the meal when you hover your wrist over your plate and snap your fingers. Nothing to open. Nothing to remember. One purchase. No subscription, ever. zib.band

About

AI Calorie Tracker

Features
Read full description

Photograph your meal and see its calories and macros. Caltracker separates the plate into individual items, estimates each portion in grams, and gives you the calorie, protein, carb and fat breakdown. All you do is take the picture. A camera isn't always practical — so there are three more ways to log: • TYPE IT — "200g chicken, a cup of rice and broccoli" is understood in one line • SCAN A BARCODE — packaged food in seconds, free on every plan • SEARCH — 1,100+ foods, each with its source, live product search and menus from 20 US restaurant chains YOUR DAILY CALORIE TARGET It works out how much you should eat from your height, weight and goal. What matters more is what happens next: it updates that target itself, from what you actually eat and how your weight actually moves. Most plateaus are just a target that stopped fitting you. TREND, NOT THE SCALE Day-to-day weight is mostly water. Caltracker plans from a smoothed trend line, so one bad morning doesn't move your target. YOU CAN SEE HOW SOLID AN ESTIMATE IS Most apps hand you a single number and never say where it came from. Here every estimate shows how confident it is (±kcal) and what it assumed: cooking oil, portion size, the sugar hiding in a sauce. If it's wrong, fix it in two taps and the app learns your portions. A WEEKLY COACH "Weekends are undoing the week", "protein is falling short" — findings pulled from your own numbers, not advice copied off the internet. ALSO • A fasting timer for 16:8, 18:6 and 20:4, and nutrition-label scanning when a barcode isn't found • Siri and Shortcuts, plus an Apple Watch app for your day at a glance and quick add • Two-way Apple Health sync • Home Screen and Lock Screen widgets • Water tracking, recipes, streaks, CSV export • Works fully offline, no account needed • No ads, on any plan WHAT'S FREE Logging, barcode scanning, the dashboard and your full history are free forever — plus three cloud photo analyses to try it. When those run out, photo logging keeps working on the on-device model. Nothing gets locked. WHAT PRO UNLOCKS Cloud photo analysis with portion sizing, the self-updating calorie target, the expenditure chart that measures your real burn rate, unlimited recipes and the full weekly coaching review. SUBSCRIPTION Caltracker Pro is offered monthly or yearly — both start 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, and your Apple Account is charged within 24 hours before the period ends.
