Schematic diagram to show the steps involved in iterative co-design, testing and implementing a prototype using a HCD approach. This is an illustration of the co-design iterative process that was used in the design of the LIFE app, emphasising the cyclic process for developing and refining the prototype with feedback from users as testers until the LIFE app is ready to be published on the Appstore/Playstore (adapted from Gibbons, 2016) [42]
