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)
