Spring is just about to begin. I've cancelled my Zwift subscription (for the time being). It is time to get out on the road . . . but we all know there are probably a few trainer days left. I was an early adopter for Zwift, but I have to admit that I've become bored with it. I like the variable "terrain" that Zwift provides, but the social and scenery and game aspects don't do it for me anymore. It's not a bad platform, but again, I'm bored with it. So, before I pay $15 to reactivate for one or two spring rides, I have a question . . .

Is there a decent smart trainer program / app that I can download to my laptop -- that doesn't require an on-going subscription or a continuous Internet connection? I would like to have the variability of resistance that I get from Zwift, but I don't need volcanoes or races or multi-national thumbs up. Is there a good trainer program that "stays in the room" so to speak? I don't need workouts -- I plan those myself. I just want a platform with variable terrain / resistance and two-way connectivity and control for the smart trainer. Ideas?
