Useless...
...because on iOS the functionality is limited to the few apps that directly support Textexpander or the apps own keyboard. That wouldnt be so bad if only the keyboard actually worked. In practice it is so completely bug-ridden that it is unusable. As always the smile is too lazy to update the application. Dont buy this. Textexpander was great on OS X (even classic before) but is almost useless on IOS.
