CatKey is the only iOS keyboard dedicated to Catalan language support. When Apple removed Catalan spell checking in iOS 17.4, millions of Catalan speakers lost a basic tool. CatKey brings it back - and makes it better. BUILT FOR CATALAN SPEAKERS CatKey (teclat catala) was created because no existing keyboard treats Catalan as a first-class language. Gboard and SwiftKey support 75+ languages but none offer dedicated Catalan spell checking. CatKey is Catalan-first, not an afterthought.
