Do I need a smartphone to participate? Yes, you need an iPhone or Android phone. If you have wifi, an iPod Touch, iPad, or Android tablet can also work for check-ins. You can download the app for free from the App Store or the Google Play store. Have more questions? Submit a request 1 Comments Date Votes 0 Maria Virginia Concio December 28, 2014 17:31 Hi!
