After using DGT GTD & ToDo for a while, I’ve uninstalled it. The app itself is well done and works well but the syncing portion causes issues: tasks not syncing properly, repeating tasks once checked off on the phone and synced to Toodledo, disappear.

Now both programs are still alpha and if the issues are worked out, they may very well be great programs. Until then Ultimate To-Do list is the way to go.
