Nujjer is a digital behaviour change intervention, consisting of the nujjer app and a Bluetooth enabled nujjer wristband. Nujjer monitors the user’s activity, sleep and eating frequency and provides personalised, motivational feedback through instant messages. Version 1 app has been developed for a clinical trial in London, UK for people who are at high risk of type 2 diabetes. This Version, 1.1, is the latest development of the app. Buddi has collaborated with King’s Health Partners (KHP), a well-established and highly regarded clinical institute in the development of the content of the messages. The theoretical framework behind nujjer incorporates planned behaviour for initiation of behaviour change, and motivational interviewing to support participants in forming healthy intentions. This encourages self-monitoring of lifestyle behaviours and provides biofeedback on behaviours. The objective of the clinical trial is to demonstrate that nujjer, a digital behaviour change intervention, encourages the user to increase their activity levels, decrease their weight and reduce their risk level of type 2 diabetes. Following the trial, we expect this solution to be tailored for use by healthcare systems e.g. the NHS in the UK, to help prevent the increasing rise of type 2 diabetes.

The user can log “events” using the functionality on the homescreen. When CRAVE and LAPSE functions in the app enable users to ask for support and encouragement, or be distracted, when feeling particularly vulnerable to a relapse of their lifestyle change. Nujjer learns over time what helps each individual in different situations to avoid lapses and how to predict a situation in which a crave is more likely. Users select ACHIEVE in the app when they feel they have achieved a goal and receive positive feedback on this action.

The app displays both day view and week view charts for the user to compare their activity, sleep and events. The app also enables users to enter specific goals around weight and daily step count. These are logged and further goals can be set over the course of using the nujjer app and nujjer wristband.

The app “learn” section provides users with a curriculum of learning modules, which have been developed based on proven educational topics in the diabetes prevention space. The user will receive messages directing them to different modules over the course of the 12 month trial.

The app is only functional when connected to a nujjer wristband.
