BloodSugar: Diabetes Tracker

BloodSugar – your blood sugar and how your meals affect it BloodSugar is a lightweight, clear diabetes diary for your blood sugar. Your readings before and after eating are what it is all about. For particular foods or meals you can record several readings and, over time, see how your body responds to that specific food. HbA1c, blood pressure and weight are covered too. Ideal for people with diabetes who want to track and understand their own numbers. No sign-up, no account, no cloud – all your data stays encrypted on your device.
