Description of intervention(s) / exposure
Participants will use an app for six weeks during physical activity, developed to provide guidance on carbohydrate and insulin dosing for young people with type 1 diabetes.

The app is broken down into two main sections. The first is the activity log where participants will enter the type of physical activity they will be completing. They will be guided through a series of questions related to the activity, the timing of their last insulin bolus, and their blood glucose level before the app provides them with advice on the amount of carbohydrates to consume, and any adjustments to their basal insulin. The second section contains additional educational information on treating hypoglycaemia, pre and post exercise advice and food advice. The advice and educational content is sourced from the International Society for Paediatric and Adolescent Diabetes (ISPAD 2018) guidelines, the American Diabetes Association (ADA) 2016 guidelines, and Lancet guidelines (Riddell et al 2017).

Participants will be instructed to use the app for all physical activity they take part in during the six weeks. The type of physical activity is not set. The additional educational information section is available for participants to use at their own discretion.

Participants will download the app at visit 1. This visit will be attended by an endocrinologist, and a research assistant or nurse.

The App has been co-designed with the target population for this study and being trialled for the first time in this study.

Google data analytics will provide information about how frequently the app is being used, how long users are interacting with the app, and time spent on specific features of the app. This study it to test the acceptability and usability of the app and obtain feedback from young people with T1D. It is not to test the adherence to the advice.
