What’s new
Version 2.6.0 · Updated October 21, 2026
Practise your mistakes whenever you like – and start over if you want to. - New: Extra round in the Review List – drill your mistakes as often as you want. A correct answer never pushes a card further out in your schedule; a wrong one sends it back to box 1. - New: Reset everything – one place on your profile to reset lessons, the Review List (including every counter) and your statistics. XP, level and streak stay. - New: Landscape layout – turn your iPhone sideways: exercises, games, flashcards and exam practice now fit the wide screen. Also in this update: - Exam practice tells you clearly when your daily limit is reached, instead of showing an error. - The verb conjugator works again on older iPhones. - Small fixes and improvements. Thanks for learning with KasusKnacker!
