Thanks for your review!
Concerning your idea for a sale for Oovium for Mac: I have been meaning to somehow created a sale for existing Oovium users. My plan to implement this was to schedule a day or so period to reduce the price from $30 to $10 and then create a message within Oovium itself letting people know the app was currently on sale.
I need to roll out a new iOS version however to accomplish this and have been a bit distracted recently so I'm not sure when I'll be able to get to this.
At any rate, in the interim, send me an email.
