Log a meal in seconds and see what it could mean for your blood sugar.
Glucoach is a simple food diary for people who watch their glucose. Pick a food from the built-in database or type the nutrition yourself, and Glucoach estimates the carbs, calories, and possible glucose impact of the meal. Save it, and your days and weeks build into a history you can actually read.
Made for prediabetes, type 2 diabetes, low-carb eating, or anyone who wants to understand how meals move their blood sugar.
