We thought it would be interesting to capture what people are seeing on their iPhones and Androids. While it is a lot of screens, it does provide a complete experience that is much easier to navigate for a mobile user than a full website. Also, note that RunSignUp auto-detects if the user is on a mobile device and presents the mobile version of registration and has done so for over a year. Watch for upcoming enhancements this summer that should make us an even more obvious choice for races who want to make registration easy for mobile users.
