I am a long time user of the desktop app and it is extremely frustrating to have effectively a non functional and unreliable app in the form of DTTG.
Each time an update is released I try it and it works once or twice and then sync fails or the data stored is just not transferred properly.
The solution is obviously evernote or a range of iOS apps which is a shame as firstly I have spent time and money on DTTG and I actually like the intention and style of the suite of apps.
However you do yourself no favours with an unusable app in the iOS mobile sphere.
