### 1/5 — Scamware

*2015-11-15*

After opening this app i had a"message" in the app that advertised I had been selected to test the new iPhone 7 - apparently releasing Nov 2015!

 It's opening a window to what looks similar to an Apple site address but is not. I unloaded and I'm uninstalling before getting any more scam invites.
