(Update11/21/2014) Still broken and still no response from developer to submitted incident. Removing from phone and PC. Sad, was a useful tool. (Update - 10/24/2014) Still broken for iOS8.x. Logged a ticket with support in Oct. 8th and received the auto response. Since then, crickets. I really liked this tool but it seems clear the garage door has been closed. Removing app and looking for something else. (Older post below) (FYI - I use WiFi sync) Great tool prior to iOS6 and iPhone 5. Crashed frequently after upgrading iPhone 4 to iOS6, but was usable. On iPhone 5 it crashes on startup all the time. I have been unable to consistently get into the app, even after removing/reloading app several times. For the most part it crashes on boot far more than it actually works. For iPad 3 with iOS6 I dont seem to have the same problem. It hasnt crashed and seems works fine. Suggestions - Make sure that OneNote on your computer is the master copy. You may lose a few things if input them directly on the phone, but if you have to remove and reload the app at least you can resync. I really like and rely on this tool. Once its fixes for iOS6 and iPhone 5 I will up my rating to a 4or 5.
