Gestures on trackpad dont work

This would be a truly wonderful app if it were ported well to the Mac. Im sure it works great on the iPad, but it doesnt interpret trackpad gestures on my relatively new 17" MBP.
I cant zoom out by "right clicking" as they put it. The secondary mouse button gesture doesnt work with the track pad so Im left clicking the home icon to zoom out, which would be OK - if it worked. Clicking on the home icon doesnt zoom out, at least not after using the app for more than 60 seconds. Zooming out works once or twice then stops working. Futhermore, the app doesnt understand the trackpad enough to slice sections.

Overall, I am disappointed because I think to use this I have to haul out a mouse and set it up - JUST for this app. I simply havent had time to do this level of beta checking for the developer. I want to dispose of mice since the trackpad is so responsive and accurate as a human interface. But this app makes it almost impossible to do basic navigation using the trackpad. I have a MacBook Pro - not an iMac. I need to use the trackpad.
My rating would instantly go to a 4 if the app simply understood the trackpad.
