My tour was recorded very inaccurately. What can I do if many straight lines are shown in my tour?

First, make sure that the location permission is enabled and set to “accurate.” The quality or accuracy of the recording depends largely on the GPS sensor used in your smartphone. Additionally, local conditions such as densely populated urban areas, tunnels, underpasses, etc., can interfere with reception. You can inform yourself, for example, using free location apps like GPS Info or GPS Data about the accuracy of the built-in GPS sensor.
