I don't think the application will ever be updated again since the developer is out of business and there is no one to contact to. I did find the software listed on the App Store, but when you visit what appears to the support website, a DNS error is displayed instead. The same goes for the official website as well.
Because of that, it's impossible to say if the software will be updated in the future and you might have to find another application since this one is not available anymore.
