The app takes forever to load. I live 2-3 miles away from PF and as I'm pulling out of my driveway I have to open the app. so that hopefully by the time I'm entering the the gym and at the scanners I can scan myself in. Network/5g/4g/wifi doesn't matter. If you open the app when you pull up to PF your gonna stand there at the scanner waiting for it to load up and there's always a line.
