Ratings and Reviews

Useful, enjoyable and educational


This app is quite useful. I'm giving four stars because it can be so much better! Usually when I add an app to my iOS/OS, I add that app then use it, not having to read the instructions. This app is not quite different except that it is integrated into the widgets, which I think is ok, however, I'd prefer this app flow the following way; I'd enjoy this app much more if, while continuing to have the widget to collect the words, also have the ability to 1) create custom dictionary on-the-fly (from all words), 2) access app from several locations (this can be completed by adding words from all areas of iOS, as part of the "lookup" and "open using" menus,) 3) "lookup" to see previously added/defined words and similar past used words (from within iMessage, Notes, Mail, etcetera), Force-Touch lookup/add-to, and 4) access word/definition in the share menu, "share to" so that a user can add/define during the share-with (or open using) process(es). 💫

No Export Option

Evan I Am

Wordio isn't bad. I *love* the concept -- it works and it's clean.
HOWEVER: there is no export option. This is probably the app's biggest fault, as it renders itself not cross-platform friendly.
Wordio supports only Apple devices -- there is no version for other operating systems, no webapp, browser extension, or even quizlet integration -- this *would* be understandable, as these can require additional systems or skills on the dev's end, but combined with a lack of options to export the data, it pigeonholes users.

Very convenient app. for voca studying
