Apologies if this qestion is too basic but it would be very helpful to be pointed in the right direction.
I would like yo create a calculator style app that anybody can use (for instance, think of a Body Mass Index calculator. I really don’t want people to have to go through a sign on process as I think this will be a hurdle to adoption.
Once in the app, I’d like the user tobe able to select some preferences pertenant to them (in the BMI example Gender, Age group, height and weight) and then make a calculation.
I can get the app to work when only one user is using it at a time, however when multiple users load the app their results change based on what another user is typing in.
Is there a solution in Glide without having to get users to sign in and create profiles?
Many thanks and apologies again if this is too basic a question.

Yes, User Specific Columns.
