I would echo everything JP says. FlickType is terrific but I was disappointed when the Spanish option language was removed, having re-appeared very briefly some months back.
Obviously, I don't know how difficult it is to incorporate additional languages but I do know that the Spanish option worked very well when it was available.
Flicktype is so good, how can we help localising it in other languages? How much would it cost? Could you set up a crowdfunding for this? How many would be interested? Even though it's hard to tell as very few non-English speaking users know about this application.
I was so disappointed when Flexy drifted from its original goal, and became almost unusable to voice-over users. So I really hope in Flicktype now.
