A child copies the letters of a word off the page, and EaseKid Dict gives back a picture, the word read aloud, and a meaning written for their age. Or they say a word, and get its spelling. Free, with no ads and no account.
A letters-only keyboard, so a child who can copy the shapes can look a word up before they can read it.
Every answer is read aloud, because the child this is built for cannot read the answer yet.
Words are suggested as the child types with no network needed, and words the device knows show their short meanings offline.
Say a word and get its spelling, with the same-sounding ones offered too, since flower and flour sound alike.
