Not working
It gives you an option to look at a calendar to see the previous days and to sign in, except your not actually able to sign into the previous days or see what classes were available on those days.
Response from developer
Hey mate, when you sign in to class, the gym can approve it or not. It is a feature that the owners of gyms like. It allows the gym owner to really confirm you are present in the class and not just a guy who is trying to get more presence. When you check in on a previous day, maybe your gym didn't check it again, and your presence is on pre-check-in. I will work on it to make it clear in the next release. Thank you for your feedback.
