I tried Mywhoosh when the weather went to shits at around the end of September/early October. Tried it on the iPhone first, it was okay. Then installed it on my Macbook, terrible experience. Kept crashing all the time. Cannot recommend it for this unfortunately. Also, not a big fan of the graphics, still seems to me it's in an early Beta state. Zwift, even though I hate to admit it, does not have a direct competition at this very moment imho.
