I just added remotestorage support to my todo list app “synclist” (still a working title, suggestions are welcome).
It is quite optimized towards touch user interfaces, I use it on a daily basis on my Android phone.
Your data is automatically encrypted, though I am not sure about security as I only use the default RNG and could have made some mistakes in the implementation.
One word about the buttons on the item menu, as they are not as intuitive as I wish: The first (up-arrow) lets you move items by dragging on it, the second is for editing and the third for moving to a different category.
It would be great to get some feedback on the application!
Ah and by the way: Adding RS worked like a charm, thanks for this great library!
