This update addresses a check ride problem. ForeFlight 14.5 just added a feature to change the ruler to show either magnetic or true north. Until this update ForeFlight only showed magnetic north. Applicants for a Private or Commercial pilot certificate (license) are required to produce a navigation log that starts with true north and continues to find the magnetic heading. I find that some applicants have used the ForeFlight magnetic heading to start this process which then introduces an error in the result. Students tend to know the nav log process early in training but then forget as they use ForeFlight (or similar app). The NavLog process should be reviewed prior to check rides. This update in ForeFlight might help however applicants should know the difference between true and magnetic north. And BTW, ForeFlight is totally acceptable during a check ride but know how to get from A to Z.
