Yes, I think most of our testers have already used the Mac version of OLLY, so they are familiar with the features. We were curious though to see how intuitive the ipad interface would be for someone who had never encountered OLLY before, and didn't even have video tutorials to help get started.
Our Mac version has contextual help scattered throughout the system, but that sort of thing is frowned upon in mobile devices, so the best we can do is create a "Getting Started" tutorial at the beginning, when a user first signs in. We wanted to make sure we had all the features and interface suggestions smoothed out before making that though.
We are resolving the crashing issues right now, so hopefully our beta testers can just concentrate on features and interface usability. But I can certainly understand if you want to just wait until everything is worked out before using the app again. You probably have enough to do already!
We are not pressed for beta test slots though, so I will leave you on the list in case you want to give the app another try in a month or so (there will be some updates to install).
Thanks for trying out the beta though - and best wishes!
