Good when it works...Always some BS with it going down or it unsubscribes me.
by: Review created: Oct 20, 2016
Review:Paid $230+ per year, I'd love to be able to simply login with no major issues. Too bad that not the case. Support sucks as well, never usually hear back from anyone. 

Good app, horrible service
by: Review created: Oct 07, 2016
Review:Good app when it works - very helpful! But customer support is horrible or nonexistent, outages occur often, and prices vary wildly with no warning.

Support is questionable and program is unstable
by: Review created: Oct 05, 2016
Review:Take 24 Hours to get support and the Program is unstable.  Their Solution was to unsubscribe then subscribe again.
