Back to the original topic: I'm seeing how far through the winter I can get on free trials before I pick one to pay for. Fulgaz is ok, Rouvy the video freezes after a little more than an hour, and Zwift is an incredibly heavy app. I deleted everything extra off my phone and got it to work once, now it wants more memory. What other reasonably lightweight programs should I try? Mostly interested in training, not recreational riding.
