An iOS app - mainly for Type 1 Diabetes patients - to ease the calculation of sugars, regular carbs, fat-protein-units (FPUs) (aka extended carbs, e-carbs or fake carbs) and their matching absorption time. Fat-protein-units are known to be the reason for late blood glucose rise. Many semi-automated insulin pumps allow you to enter these e-carbs, so that the pump can deliver more insulin. Main features are: - Maintain your own, personal dishes and easily compose meals containing as many dishes as you wish - Search for products in OpenFoodFacts food database - Scan barcode of products - The app calculates your meal's total calories, sugars, carbs, extended carbs (e-carbs) from fat and protein (FPU - Fat Protein Units), and recommends the time your body will need to absorb these e-carbs (aka. absorption time) - Store your sugars, carbs, e-carbs and/or calories in Apple Health (only on user request, no automated storage) for utilization by other apps - Synchronize your food list across all your iOS devices via iCloud (optional)

Track calories with Otto, the dramatic otter who needs you to log dinner. OttoFit turns food logging into something you'll actually do. Snap a photo of your meal, scan a packaged barcode, or just type what you ate. The app estimates calories and macros in seconds and adds them to your day. HOW LOGGING WORKS - Photo scan: point your camera at a meal, tap once, and get a full nutrition breakdown. - Barcode scan: works on packaged foods using the OpenFoodFacts database. - Type to log: describe what you ate. "Chipotle bowl with rice, chicken, double salsa" works. - You can even scan a picture of nutrition facts or the receipt from the restaurant you ate at (just be sure to mention the name) - Manual entry: for when you already know your numbers. MACROS THAT MATCH THE MATH Protein, carbs, and fat tracked per meal and rolled up daily. Calorie targets are calculated from your goal and adjusted for your activity level. No arbitrary defaults. LOCK-SCREEN PRESENCE A Live Activity shows your daily calorie progress on the lock screen with a tap-to-log button. Home-screen widgets show the same in small and medium sizes. EDIT AND FIX Logged something wrong? Tap any entry to edit calories, macros, or the meal name. Backfill meals you forgot from earlier in the day. STREAKS, WEIGHT, AND TRENDS Log every day to build a streak. Log your weight whenever you want. See your weekly calorie trend and weight trajectory side by side. A MASCOT WHO PAYS ATTENTION Otto is an otter with opinions. He celebrates indulgent meals, teases the healthy ones, and gets dramatic when you blow past your calorie budget. His reactions are based on math, not morals. Eat the wings, just log them. PRIVACY All your data lives on your device. Food photos are sent to our server for analysis and immediately discarded. We don't ask for your name, email, or login. Anonymous usage analytics only. FREE AND PAID The app is free to download and use. The AI scan features (photo, describe, barcode) require a subscription.
