What's New in Lectio

1.0.5

September 12, 2026

Long sources become a lecture series: a big PDF or article now arrives as 2–4 short parts you can listen to one after another. Take the quiz between parts, or turn auto-quiz off in Profile and let the series play straight through. New Progress tab: where you left off, your review queue, and honest quiz scores per lecture — plus your streak, daily goal and exam date in one card. Smarter quizzes: every lecture carries three separate question sets; retakes bring fresh questions, then the same ones back in a new order. Finish your flashcards and jump straight into the quiz. Faster, better narration under the hood.
