Love the concept.
Sounds like a useful app for people like me who love traveling so I was looking forward to trying it out after reading an article about it on Geek Wire. Unfortunately, since the only way past this app's splash screen is to create an account by signing in via Facebook, I cannot even get a taste of how it works. Give users an option to login with Facebook or by creating an account specific to this app; give users the ability to add friends manually; and if a user joins the app's community first, then wants to link social media accounts afterward, give them an option to do so independent of account creation.
New search functionality, bug fixes and improved user interface!
