The ADDN mobile app is available to be downloaded from the iTunes Appstore. Use this app to compare your glycaemic levels (HbA1c) and body weight (BMI) with children from your age group who also have type 1 diabetes.  This app compares your HbA1c and weight to the average HbA1c and weight of children and teens who have their diabetes information stored in the ADDN Registry. You enter your details to get feedback on how you compare with the ADDN group, and know whether to contact your diabetes team to help you aim for and reach a level of diabetes control that is right and safe for you, or help you towards reaching and maintaining a healthy weight. Give it a try!
