What's New in Refine
1.9
October 30, 2026
What's new in Refine 1.9 • Share what you learn: after practice or a check-up, share a replay of your map as a video, or a highlight from the full read as an image card. • Quiz a friend: pass the phone and a friend asks you a chapter's questions and grades your answers in plain words. • Invite friends: every share carries your invite link, and a friend's code pastes in with one tap. • On iPhone Duo: open it to read a chapter beside its lit map, add a sentence to the map, see two books side by side where they share an idea, and stand it half open for a check-up. • The player uses the whole window on iPad and Mac. • A new welcome that shows how the map works before you start. • Long textbooks build more reliably, plus smaller fixes throughout.
