Rally Tripmeter funktioniert nicht

This app helps rally drivers to measure distance, keep time between time controls, take time on special stages, keep you near your target speed on TSD or Regularity rallies and much more.  Rally Tripmeter is an application that makes traditional rally trips obsolete!  A must be app for every rally driver, even if you own a professional rally trip as you never know when you might need a backup!  An app for rally (co)drivers developed by a rally driver.  You can define the special stages and keep just on time for the checkpoints.  Be a Winner, use Rally Tripmeter!  Now even more useful for TSD and Regularity rallies as there is two modes dedicated for them.  Note: Continued use of GPS running in the background can dramatically decrease battery life.  Works well both on small and large devices due to automatically resizing texts.  And the best thing, this app does not weight anything!  Rally Tripmeter offers a Free 60-Day trial, after which a licence is required to be purchased.
