Hollr - Instantly invite your friends!

Have you ever felt like inviting your best friends to whatever you are doing right now?
Now you can do this with a single tap!
Hollr lets you select the friends you want to send the invitation to (they must be Hollr users too), and with a single tap you can send out a notification to your friends letting them know that you want them there.

The app uses Facebook for authentication. The friends you see in the application are the friends who also registered with Hollr AND are your Facebook friends.
