It's not user friendly. You can't use the app to track macronutrients or calories. You can't input your own exercise. You can't create meals. It only wants to know how many servings of milk, fats, vegetables, starches, sweets, meat and fruit you eat as if all foods within those categories have the same impact on my blood sugar. Will broccoli spike my blood sugar the same way corn does? Sweet potatoes and white potatoes have different amounts of carbs and sugars per serving. Why would they both count the same?
