Love to record tracks with barometer altitude Best app to record tracks with barometer altitude for better precision.
Great for marine charts Nice features for use with NOAA RNC marine charts
not a refined app the offline maps are neither fully nor nicely shown. the symbols in the icons are an absolute mess - you can't tell what each icon is for. After paying almost 10€ for the app I ended up removing it and installing Locus for almost another 10€.
