Multiple attempts were made to contact the app developers by email informing them of the inability to use the app, but to no avail. This app is a scam. Enough said. There is no way to sign up. Any attempt to do so will crash the app. The company itself has very little credibility in the iOS field. They are a failed bicycle "uber" equivalent that hasn't feen active since 2014. I will be emailing apple for a refund and reporting this app.
