I've been using trainer road for about a year and really rate it. But the fact I have to set up my laptop each time is a pain in the proverbial.
That are apparently developing an android app but news since September so now looking for an alternative.
What else is there out there I could use?
I may or may not be developing an android based training app just now (I am). It's not going to be a trainer road clone (never used it), but it should at least be useful. It's not feature rich at the moment, but I'll be looking for some alpha testers soon who can try it on other hardware. Drop me an email if you're interested.
Depends on just what you want to do. And what sort of trainer are you using, with what sensors.
Try IpBike for a fairly simple cycle computer style app.
