Daily Mandarin
Learn Mandarin, one character
a day — right from your Lock Screen
Daily Mandarin teaches you Chinese vocabulary with spaced repetition, so review timing adapts to what you actually know — and today's character shows up automatically on your Lock Screen and Home Screen, no need to open the app.
Available on iOS. Android coming soon.
Everything you need to actually stick with it
Built around the one thing most language apps get wrong: showing up every day without feeling like a chore.
Lock Screen & Home Screen widgets
Today's character appears automatically throughout the day — glance at your Lock Screen, no need to open the app.
Full HSK 1–6 vocabulary
Thousands of characters and words across every HSK level, with HSK 4–6 available as an optional add-on when you're ready.
Spaced repetition that adapts
Built on the SM-2 algorithm — review timing adjusts to what you actually know, instead of a fixed daily deck.
Simplified & Traditional
Switch character sets anytime — the whole app, including your widgets, updates to match.
Streaks & a review calendar
See exactly which days you showed up, with a calendar view of your review history.
A reminder, on your schedule
Optional daily notification at a time you choose — never a surprise, always in your control.
How it works
Glance at your widget
A new character appears on your Lock Screen or Home Screen throughout the day.
Tap to review
Open the App, reveal the meaning and pinyin, and see it in a real example sentence.
Learned it, or later
