After purchasing Merlin with the web and iOS sharing modules, Im disappointed with the functionality of this app and most of all the stability. First your computer has to be on, connected to the Internet and running Merlin to make any changes on the iOS version. The Gantt chart does not show dependancies and orders groups and projects based on start time and not how you have them in your actual plan, but the worst problem is that the app crashes all the time. It seems to be most stable right after a sync. I believe they have a good product here, but it needs a lot of attention, especially frustrating considering what you have to pay to use it.
