Members

Use more than one gym

One login covers every gym that has you on their list under the same phone number.

Steps

Log in as normal.
If more than one gym has you as a member, Select Your Gym appears. Tap the gym you want.
The app opens on that gym and stays there — your details, attendance, payments and sessions are all that gym's.
To switch to the other gym, tap Sign out and log in again. The gym list comes back and you pick the other one.

Both gyms have to have you saved under the same phone number. That number is the only thing that links them. Different numbers means two separate logins, each set up by its own gym.
There is no switch-gym button inside the app. Signing out and back in is the way. It is quick — the same phone number and password work for both.
The app remembers your choice, including after you close it. You will not be asked again until you sign out.
You can only check in at the gym you are currently in. Scanning the other gym's QR will not work until you switch.
If only one gym has you on its list, you never see this screen at all — the app goes straight to your home page.

You only see one of your two gyms. The missing gym has you saved under a different phone number. Ask that gym to update your number to the one you log in with.
"Your account is not linked to any gym." No gym has a member record for your number, at all. Ask your gym to invite you again.
You are dropped onto Select Your Gym in the middle of using the app. Your phone cleared the app's stored data — clearing browser data or a long gap will do it. Pick your gym again; nothing is lost.
"Failed to load your gyms." A connection problem. Tap Sign Out and log in again.
The wrong gym's details are showing. You are signed in to the other gym. Sign out and pick the right one.
