Hei Zetor, thanks a lot for your feedback
so, currently im working on different minor bugreports and code rationalization, on adding charting functionality (so you can also see your max HR : ), and adding more HR chest belt support (checking how good the sports tracker one works atm). all this i plan to push out really soon (weekend maybe? i hope..)

After that, i will most likely follow the todo list you can see on the website, and step count is definitely one of the things
But i was thinking to first work to add maps functionalities and the limits.
But i believe steps will come soon too, together with a better gps filtering.
I have also an idea to get accurate altitude (if you noticed, the gps altitude is just terrible), but it seems a little bit a long shot. I will give it another try tho

by the way, why do you want GPX? some soft reads it, or you can upload it to sportstracker?
