UsynligO is an orienteering app designed for iPhone users. It offers a unique way to participate in orienteering races without physical flags. The app allows you to select a map, start the race, and navigate to control points using the printed map. Instead of physical flags, the app tracks your location and alerts you with a sound when you reach a control point.

With a built-in compass, UsynligO eliminates the need for additional equipment, making it convenient for users. You can request hints for direction and distance if you get lost. Additionally, the app enables you to publish your race results, including elapsed time and split times, on the UsynligO server. UsynligO also supports creating and sharing custom maps on its website for other users to enjoy.
