One of the best. All the features you need to plan/estimate time easily. Drawing route is easy thanks to the option that magnets the line on existing paths on the map. Good job! Only thing I think could be improved is the UI. But it does the job.
I used this app to get me along the Maclehose Trail part of the HK4TUC when my regular GPS unit failed and I needed to get back on course. I reversed the inbuilt trails but will share my versions. I needed to conserve battery so I just exited the app when on easier parts of the trail, then followed the trail with locked GPS and off-course alerts with the screen off. This is a great app, very reliable even on my old phone with no SIM card.
excellent for hiking in Hong Kong
Great app for hikers. Have been using it for 2 years GPS function is easy to use. Good for planning your own routes too.
If the first fix is a coarse location, move the map again when obtained the first fine location.
