I completely agree. What's the point of having a mobile app which only performs part of the functionality of the computer program? At this point in the development of the mobile app, it makes no sense for me to waste my time syncing everytime I log out of the computer version. I cannot use the mobile app in the same way I use the computer version. Quicken is befind the times on bringing their product to the mobile world. I have banking apps which let me accomplish exactly the same thing and even more on their app as I can when logged into their web site on my computer.
