This has the same design as http://mouapp.com which has been on the market for a long time now.

Mou is donation based so you can try before you donate. The developer is very responsive and the app is constantly updated.

I really don't get it.

Chipping in to say the same thing. Mou is a great product and I've convinced a number of people in my office to start using it.

This feels like a different shade of the same idea.

on top of that Mou supports custom styles, which I see no mention of from Erato. I happily donated to Mou, and really don't see why anyone would choose Erato over it.
