Essential for getting out and about and following the public byways

Incorrect information can put you in danger. Like many older UK residents I changed measurements into miles and feet. The app gives measurement in meters but says its in feet. I should have noticed but 200m and 200ft climb is a big difference when hiking with a 10 year old child. resulted in me carrying 2 Rucksacs. Please be careful until this is fixed. Route planning show elevation graph in meters but labels it feet!
