A new Today's Study - Each word's review date is now set from how long you are likely to remember it, so you review just as it starts to fade. - Check results are rated Hard, Normal, or Easy, and the first review after learning comes 1, 2, or 3 days later. - Reviews now come on the scheduled day, whatever time of day you study. - Words you miss twice in a review now start over, as they should. Multiple study schedules - Create a study schedule for each source (book) and study them side by side. Daily new and review counts, the study calendar, and badges are kept per schedule. - A word in several schedules is reviewed in the schedule where you first learned it, and the other schedules show it as "in progress". Study details - Tap "Details" on a schedule to see word status (Waiting, Learning, Stable, Restarted, Completed), reviews for the next 14 days, words by view count, and daily 1st- and 2nd-try correct counts. - Completed words are now words you have kept up for more than 45 days. The estimated finish date now shows when all words will be completed. - Review cards show how many times you have seen the word. Backup - Your Today's Study progress and schedules are now backed up to iCloud, so a restore brings back everything up to your last session. - Your existing study progress moves to the new system when you update.

Your word list is now organized by part of speech • Meanings are grouped by part of speech (noun, verb, and more). • Cards show each meaning's usage (informal, slang, regional, and more) and word forms (plural, past tense, and more). • A meaning can now have more than one example sentence.

New Feature Today's Study — Smart Daily Review - Every day, the app automatically selects new words and words due for review, guiding you through a single study session. - New words go through "Preview → Check," while review words go straight to "Check." - Words you get wrong aren't skipped — once a full round finishes, they're regrouped and re-tested in the next round (shown with a "Round N" screen), repeating until you get them right. - Bulk-imported words can be quickly sorted as known or unknown in the new Word Queue Check screen. - Your progress is saved if you leave mid-session, so you can resume where you left off or start over. - A study calendar heatmap shows your study activity over the last 5 months at a glance. - When a session ends, you can review every word you studied that day, see how many times you missed each one, and tap any word to open its detail card. - Fully customizable: daily new-word count, daily review limit, preview/check timing, and more.
