Dear @danros, thank you for your interest in the Workout Reserve.
It is currently available for cycling (with power) and running (with speed). It works best if you sync your profile before going out for a session. We are not releasing a version for the other modalities such as swim, but maybe in the next future we’ll be adding rowing to the list.
When you select the activity, the app automatically refers to your corresponding profile: cycling-> cycling, and running->running.
Sorry for the incomplete/suboptimal documentation. Please, keep the comments coming, I’m quite interested in your experience with the app.
Thanks again for your trust.
