About

Kiseki キセキ

Read full description

Kiseki is an application that records the route of walking, jogging, cycling, etc., and transfers the route data to a Macintosh as GPX data for use with the Macintosh GPX display software “KIseki for Mac”. For this reason, the application has been designed to be simple, with only a start/stop button. In addition, if a monitoring area is registered, the application has a geo-fence function that pauses when the user enters the registered area during operation, and resumes data acquisition when the user leaves the area. Please be sure to select “Always Allow” to enable the use of location information in the background. For details, please see “How to Use” in the application.
