I used to have Orux maps on my phone and it gave a lot of info and does connect to ant+ sensors if your phone can handle ant+.
It's been quite a few years since I used it and the abundance of information was actually a little overwhelming for me at the time I tried it. But it was at that time pretty full featured. And the data it saved could easily be saved and exported as many different file types. I don't hear anything about lately but it is still out there.
