Account Tracker / Hill Lists / Meter Readings

Updated the underlying Database of British and Irish Hills (DoBIH) to version 17.3.

Added separate county tops lists for Scotland, Wales and England.

Added more detailed stats for tracked and completed lists, and for each month and year in the dashboard view. Swipe right to left and choose Stats.

As an example you can now track which days per month you have climbed hills on (or not, if you want to fill in the gaps).

Minor changes for iOS 15 compatability.
