Mantis Touch: The $100 mobile app.

I was looking around for ways to implement Bug Tracking. I found that Mantis Touch is $100 for the iPhone/Android/Windows phone app. For a single person that is way out of a price range although I know they hope to target organizations with a lot of Mantis users You have to buy the app for each Mantis instance you have. So if I need access for 2 different companies I have to pay twice. http://www.mantistouch.org/ This pricing seems like something we dont usually see with mobile apps. Does anything think it is way to outlandish or opposite and a very viable pricing model?
