InstaCal: The Social App for Food & Fitness Food is social. Your nutrition app should be too. InstaCal is where you see what your friends are actually eating, find your next meal from real plates near you, and log your own food in seconds with AI. Not a tracker with social bolted on, a social app where the content is what people eat. A FEED BUILT AROUND FOOD Follow friends and see every meal they log, with full macro breakdowns. Like, comment, and bookmark the ones that inspire you. Share yours on cards designed to post anywhere. You choose who sees each meal: your feed, your profile only, or only you. YOUR OWN COACH, IN YOUR DMS InstaCal Coach is an AI dietitian that reads every meal and workout you log and leaves a short note: what worked, what to fix, what to eat next. It recaps your day, week and month. Ask it anything. 6 WAYS TO LOG • Photo Scan - snap your plate, AI breaks down every ingredient • Barcode Scanner - scan packaged food in seconds • Nutrition Label Scanner - point and done • Food Search - describe it in plain English, adjust the portion, log it • Build a Meal - combine ingredients your way • Saved Meals - one tap to relog your go-to's Fix with AI: "the chicken is 8oz, add ranch." See exactly what changes before it's applied. TRACKING THAT READS AT A GLANCE Your day in boxes: calories, macros, streak, burned, distance, goals and body weight. Swipe through your week Monday to Sunday. Tap any box for full charts and the Coach's read. FOOD AND FITNESS, FINALLY TOGETHER Connect Apple Health or Strava, or type "ran 5k in 28 min" and it's logged. See calories burned next to calories eaten, with splits, pace, heart rate zones and elevation on every run. Set weekly training goals and watch them fill. EVERY ROUTE ON ONE MAP Your runs and rides draw themselves in as you scroll, and one map shows every route you've ever recorded. DISCOVER MEALS NEAR YOU Open the Map to see real meals logged around your city. Find your next lunch spot based on what people actually ordered, photographed and loved. Explore shows you plates that fit the macros you have left today. CHALLENGE YOUR FRIENDS Set a target like "run 50 miles this month" and race your friends, or go head-to-head on points where everyone is scored against their own goals. Join public seasons with the whole community. MESSAGE YOUR PEOPLE DM friends one-on-one or in groups. Reply to stories, react, share meals and workouts straight into a chat. EARN YOUR BADGES 88 achievements to unlock as you log, cook, compete and keep your streak alive. Then get your month, wrapped: a story of your meals, miles and streaks, ready to share. ON YOUR HOME SCREEN Widgets for today's calories, your streak, a one-tap Log a meal, friends' latest plates and your last workout. Lock Screen too.
