I just want to pump up this topic since I think it is really interesting and useful feature to have supported ant+ sensors. I am a cyclist, just imagine you may turn my (and many others cyclists) android phone to very powerful bicycle computer! That is really cool. I have been using endomondo and sports-tracker apps, they are nice (it is possible to connect ant+ sensors e.g. speed, cadence, hrm) BUT they don't have powerful features (which locus has) to work with maps, e.g. to cache/upload maps and to upload routes/tracks.
I believe it would be really big advantage to have ant+ sensors supported by locus app. Are you considering to implement it? I am willing to help you.
