I have bought dozens of these sort of apps over the years - none of which ever got daily use for one reason or another. Notebooks is quite a different proposition and I now use it all of the time. Filled with hidden options that really enable you to configure it to do any task you throw at it this is a solid and reliable app with many cool features. I use it in conjunction with my Synology server by synching it via WebDav and then using CloudStation to sync between the server and the Mac desktop version. Synching this way is always fast and seamless (as is the straight wireless sync straight to the Mac). I also bought the addon PDF editor for the IOS app which is superb and worth every bit of the small amount charged for it.
