Hello orux!
I use oruxmaps as a cyclingcomputer and it works great. It is possible ti display the current slope, but it is very inaccurate. I think that the interval of measurement is too short.
I mount my mobile on my bike. So i had the idea to use the pitch sensor for slope. Therefore it should be possible to set the value to zero when the bicycle is in horizontal position.
What do you think?
Dear
Berni
