What's new in 1.8 — the HSK 1 milestone: • 49 new characters — the library now covers the complete HSK 1 set, 169 characters in all. • Everyday essentials arrive: 电脑 (computer), 电话 (phone call), 星期 (week), 睡觉 (sleep), 医院 (hospital), 再见 (goodbye)… • Every new character ships with etymology, a cultural story, example phrases, and verified stroke-by-stroke tracing. One character a morning. For a year. For a lifetime.

What's new in 1.7: • Sentence quiz now shows the English translation, so you actually understand the sentence you're completing. • Fixed a black screen that could appear when starting 温故 Review. • Long-press the dots at the bottom and drag left/right to jump quickly between days. One character a morning. For a year. For a lifetime.

New in 1.6: • 温故 Review — characters you've learned gently resurface as they start to fade, so they actually stick. Revisit them in a one-minute recall. • Streak freezes — earn a freeze every 7 days; miss a single day and your streak survives. • Evening reminder — an optional nudge if you still haven't learned today's character. • Widget — tap it to jump straight to today's character, or to your review when characters are fading. One character a morning. For a year. For a lifetime.

The library just more than doubled — now 150+ characters. • Big content update: numbers 一–十, family terms, pronouns, question words, common verbs, places & directions, food, and everyday adjectives — each with its origin story, stroke order, native pronunciation, example sentences, and tone practice. • You can now build real sentences from what you've learned: 你叫什么名字? (what's your name?), 现在几点? (what time is it?), 我喜欢你 (I like you), 请帮我… (please help me…). • Smoother daily flow and refinements throughout. 知止 — learn slowly, remember for life.

Lots of new characters — the journey goes deeper. • Many new daily characters: the full numbers 一–十, plus essentials like 国, 文, 学, 看, 听, 说, 爱 and more — each with its story, stroke order, pronunciation, and example phrases. • New "now you can say" phrases that build on what you've learned (你好, 我爱你, 我会说中文…). • Smoother daily flow, refined typography, and stability improvements. 知止 — learn slowly, remember for life.

New in 1.3: • Daily reminders — pick a time in Settings and Zhizhi will nudge you to keep your streak going. • VoiceOver support for the character of the day — tap to hear it read aloud with its pinyin and meaning. • Stability and polish throughout. One character a morning. For a year. For a lifetime.

New in 1.2: • See the year ahead — a 365-day journey view that shows exactly where you are and what's still to come. • Concrete milestones — preview what you'll be able to read at day 30, 90, 180, and at the end of the year. • Trial offer front and center — the 7 days free is now where it belongs, no fine print to hunt for. • Editorial polish throughout — quieter typography, a more dignified frame for the practice. One character a morning. For a year. For a lifetime.

v1.1.2 — Tightened Pro entitlement: production builds now derive Pro status purely from signed transactions (debug override is debug-only). Prevents any future code path from accidentally granting Pro.

v1.1.1 — Streak now survives DST and timezone changes (no more lost streaks when you travel), Pro users skip the AI rate limit, AI chat now shows the real reason when something goes wrong, and a Share This Milestone button on round-number wins. Plus telemetry so we know when Zhizhi is being used.

New in 1.1.0: • 7-day free trial on the yearly subscription — try Pro risk-free. • Cleaner paywall with transparent pricing, auto-renewal terms, and one-tap Restore. • Daily reminder now prompts on first launch so you never miss your morning character. • iPad layout refined — content stays comfortably readable on larger screens. • Behind-the-scenes performance and reliability improvements. Thank you for learning with Zhizhi — one character a day, for the long road.

Bug fixes: • Tone practice examples and unlocked phrases now persist correctly across sessions • Improved AI tutor reliability — automatic retries on flaky network or rate-limit responses
