The most important indications for modifying the prototype in the various test phases.

Testing Phase	Test Participants’ Indications
	Spatial Solutions and Range of Exercises	Application Functionalities
Phase 1: Prototype test n = 9	Determining the location of path points in the area Restrictive exercise on the Market Square—location of exercise points in green areas or recreation areas Attractive form of active leisure Attractiveness of the city game—expanding information on the history of the city	Possibility of obtaining information on the number of calories burnt Change from map with paths to active map Application needs to be improved to be more intuitive Unreadable and inactive map Choice of voice or text messages
Phase 2: Field test n = 7	Recreational areas and the city park as comfortable places to exercise In public spaces, comfortable places to exercise with little visibility Favourable exercise locations that do not interfere with pedestrian traffic Supplement the application with a paper map It is important to link the exercise point to the history of the place in order to establish a relationship with the place	Audio files difficult to hear amidst the urban bustle of the Market Square
Phase 3: Stationary test n = 8	None	Volume control most convenient via phone buttons Completion of location recording for real changes in location in the field Supplementation of route information (length and waypoints)
Phase 4: Field test n = 11	Enlargement of the signs marking the exercise points, which were placed too low Helpful brochures with information on the route and exercises	Positive results of the smartwatch-linked application test for data collection and gathering
