This app is a walking trail around Sheffield exploring the life of Stan Shaw, the world-famous cutler, as well as locations relevant to Sheffields rich knife-making heritage. The trail is split into two sections: a central section that starts at the Cutlers Hall, and a northern section that finishes at Kelham Island Museum. The sections can be walked separately, or joined together to make a route of around 3.5 miles. The app is GPS enabled. This is used to show you relevant content based on your location. Please note that you do not have to be in Sheffield in order to access any of the content in the app.The app also uses Location Services and Bluetooth Low Energy to determine your location when the app is running in the background. It will trigger notifications when you are close to a location of interest. We have used GPS and Bluetooth Low Energy in a power-efficient way: such as only performing Bluetooth Low Energy scans when you are close to a location that uses Bluetooth Beacons. However, as with all apps that use location, please note that continued use of GPS running in the background can dramatically decrease battery life.
