The interface is great and I love it overall; however, I'm giving it two Stars because it won't synchronize between my Samsung phone and Ipad, despite being the same account information for each. I emailed their support like about this, and they asked for my login info, but I never heard anything back. This is a huge inconvenience because I put a LOT into the version on my iPad, and I dont, and wont, do it twice for the same application. Once this is fixed I'll happily increase the rating.
