Previous app was simple and easy to use but lacked automatic sync and browser access. The new app is much smoother and easier to use with a much updated GUI. It also syncs a back up automatically and has an easy to use web app. making customization much more convenient. The transition from old to new was painful and could have been better but now that I am up its great. New users should have a problem free transition.
