What's New in Chrono Lab

3.0.1

September 24, 2026

This update fixes about twenty behaviours. The ones you'll notice first: STABILITY • The app no longer shuts down when you leave it or lock your iPhone: you come back to where you left off. • A finished game can no longer be lost when it is saved. After a long run of correct answers on the same question, the end of the quiz failed silently: no attempt, no XP and no streak were recorded — and it happened again in every game containing that question. GAME RULES • A watch is mastered on the 3rd correct answer, not on the following round. On first launch some watches will therefore turn "mastered" without you replaying them: they had earned it. Nothing is ever taken away — not mastery, not badges, not XP. • Pack badges arrive with the quiz that earns them, no longer with the next one. • When the timer runs out, the correct answer is shown. It was the only quirk that cost you a lesson. • The time bonus is no longer lost exactly at the threshold. • The "perfect chapters" gauge finally counts perfect chapters. EASE OF USE • With no lives left, "Play Challenge Mode" and "Play Identify Mode" now actually open those modes — the two that cost no lives. • "Reset All Progress" now also clears the knowledge map and the review schedule. • The level 1 XP bar shows your real progress. • Suggestions no longer reshuffle as you look at them: stable on screen, renewed daily. • Leaving the intro quiz no longer completes onboarding. • After a refusal, re-allowing notifications in iOS Settings is now enough to bring the reminders back. If you had already re-allowed them, switch "Daily Reminders" back on once in your Profile. • And the reverse holds too: if you had switched "Daily Reminders" off, finishing a quiz no longer switches them back on. Your choice is respected. • The Collection search bar is finally aligned, and follows the text size. CONTENT AND ACCESSIBILITY • Watch spec sheets are translated into French — 188 terms across 272 sheets. • VoiceOver now says "40 mm" and "50%" instead of reading raw values. • Text finally follows the system text-size setting. • No made-up prices: only a price given by the store is shown. Your progress and your purchases are kept.
