Bootstrap Chinese Grammar

NEW: Spaced Repetition - Phrases you practise in the exercises now come back for review just as you're likely to start forgetting them – the most effective way to make them stick. - Tap the new clock button to review. A badge shows how many phrases are due. - Optional reminder on days when you have phrases to review. - Already using the app? Phrases from your past exercises have been added too, spread out so you're never faced with a backlog. NEW: "Why was that wrong?" - Made a mistake in an exercise? Tap "Why?" for a short explanation of the grammar: why your choice doesn't fit and why the correct answer does. - Shown with the correct phrase, its meaning and audio. - Explanations for every example phrase in all 185 topics. Improved content - Hundreds of improvements to example phrases, English translations and grammar notes. - If you've unlocked the full course, the app downloads the improved topics again the first time you open it after updating (once, about 90 MB). Other improvements - You can now unlock the full course straight from the App Store page. - Clearer unlock screen: one payment, yours for life – no subscription, and all future updates free. - Better layout on iPhones with a Dynamic Island or notch, and on phones with a home indicator. - Updated Help and "How to use" guide, including Spaced Repetition.
