Save trip data on iPhone and synchronizes data with OpenGTS Trips can be selected by date range (by default, app shows the trips of current day); calendar shows the number of trips for each day. OpenGTS is not required, this app can work even without connection to an OpenGTS server ( and you can set connection even after you have registered many trips: as soon as OpenGTS is configured, iOpenGTS will start sending data that was not already sent) This app uses gps in background when tracking is active. Continued use of GPS running in the background can dramatically decrease battery life.
