Suggest you have all your questions answered before you pay. They won't offer free trial and won't refund. I'm trapped.
Their website doesn't provide sufficient info about the app. I wasn't able to reach them for my questions before I was misled by their web info and purchased the app. After initial installation, I found out it was not what I expected. When I asked for refund, they won't process my request.
Again, Be very sure if the app is exactly what you want before you pay.
