"Skip" is now "Not sure". It never skipped anything — tilting back shows you the definition and brings the word round again — so the button now says what it does. New: Definition first. See the meaning and try to produce the word, which is recall rather than recognition, and closer to what using a word actually takes. New: choose how long the definition stays up, from 2 to 5 seconds. Two was enough to recognise a word you half-knew and far too little to read one you had never seen. Also: the results screen reads in portrait again. Creating a list now tells you what it still needs instead of leaving the button silent. And if you hold the phone at an angle where a tilt cannot register, the app says so instead of appearing broken.
