The laziest calorie tracker in the world. No typing. No barcode scanning. No food databases. Just snap a photo of your food or hold the mic and talk. AI estimates your calories and macros in seconds. HOW IT WORKS Take a photo. Or hold the mic and say what you ate. Or just type it. The AI responds with a calorie and macro estimate in one message. If something's unclear, it asks one follow-up — never a form, never a quiz. DESIGNED FOR LAZINESS Every interaction is shorter than not doing it. Two taps to log. One screen. No navigation menus. No confirmation dialogs. No onboarding tutorial. Just open the app and start logging. NO JUDGMENT The AI never comments on your food choices. No "healthy" suggestions. No red numbers. No "you're over budget" warnings. No guilt. Just the numbers. What you eat is your business — we just count it. NOT FOR PRECISION Cali uses AI estimates, not verified nutrition databases. If you need exact macros weighed to the gram, this isn't the app for you. If you want a rough, honest picture of your day without the hassle, you're in the right place. WHAT'S INCLUDED - Photo, voice, and text food logging - AI-powered calorie and macro estimates - Edit any entry manually - Weekly summary every Monday - Daily streak counter - Lock screen and home screen widgets - Conversation history synced across devices
