What's New in 1.3 • Conjugation panel on iPhone: see every verb and adjective form (dictionary, polite, te-form, ta-form, negatives, and N4+ potential) right in the card detail view. • Card-type breakdown bars on iPhone Stats now use the same 4-tier style (mastered / studying / struggling / unstudied) as the JLPT level bars. • Watch study history is now restored after reinstalling the Watch app — your 30-day window and recent-stats weighting come back from your iPhone automatically. • Expanded part-of-speech labels (na-adjective, adverb, expression, and more) on the Watch back face. • Stability: fixes for a rare second-launch freeze and a safe-mode recovery path if the Watch app ever hits a crash loop.
