Id really like to give this app 5 stars but there is a bug in the software that has caused the History data to be unavailable, then available for one day, and then totally unavailable again. Repeated emails to "support" to resolve this issue have gone unanswered. Until this critical bug gets fixed three stars is a generous rating.
Im upgrading my rating to five stars now as the software issues have been resolved. Now a great piece of software to accompany a great peice of hardware.
