I like this app, it’s pretty convenient to just have a barcode to sign into the ARC so I don’t have to bring my ID card. However, the app forces you to log in everytime you use it (which then makes you use Duo) and will automatically log you out after 10-15 mins. This is a very unnecessary feature (possibly bug?) since students will be using their phones when they go to the gym, not someone else’s. With both of these issues fixed I’d give 5 stars.
