For the DataSavesLives project, we wanted to find out older people's views on wearing an activity tracker to monitor their health. We asked Community Reporters in Salford and Wythenshawe to wear one themselves for a week or two and share their experiences. At the same time, participants in the weekly exercise class at Salford Sports Village tried it out to see if it would help them be more active. In this video compilation, people tell how the activity tracker motivated them to exercise more, or how they used it to learn about their sleeping patterns. Although everybody enjoyed wearing it, many said they would have liked more support with the tracker app in order to maximise the benefits.
