Wellness Gate is an accompanying app for Colgate Wellness Passport. If you are an administrator or an instructor in the Colgate Fitness center, than you will be able to sign into this app, set it up in front of one of the fitness classes, and allow students who forgot their phone to sign into the app and appropriate class, in order to get credit for that session.
As a student, make sure you see the screen saying "Youre Checked In!" so that you know you got credit for the class.
