While training with friends I want to be able to let them use Velos-ID without the reps being registered on my profile. They might want to try Velos-ID out of curiosity, or to see how fast they are so we can compare the difference between us on a same RM and RPE for example, or to challenge each other at doing the fastest lift with a fixed weight etc. I think having a “Guest” button during the Rest screen to show the Velos-ID infos (speed per reps graph) again would be a very cool update to have fun with friends in the gym using this tool.
