One device tow or more accounts

I have one iPad on my stationary bike. I’d like to be able to have two or more Swift accounts one for each of my family members on the single iPad. How do I do this?

At the present time Zwift does not offer any sort of family membership, so the only solution is for each person to sign up (and pay) for their own Zwift account. I believe Zwift may still be offering free accounts for kids, but I’m not sure of the age cutoff.
