New: a Japanese course. Hiragana, katakana and elementary-school kanji, written from memory in the stroke order commonly taught in Japanese schools. Kanji are asked the way Japanese kanji tests ask: a box inside a word, with its reading above. Choose the course in parent settings. Also new: • A character now fails after too many wrong strokes, so guessing no longer gets through • Corrected strokes in some characters, to match how Taiwan schools teach them • Credits & licenses in parent settings

Screen time that teaches Chinese: your child writes a character, then the game opens. Made by a teacher. Start free with grade 1. New in this update: • A bigger writing area on iPhone and iPad • Off-limits apps: keep your own apps locked when your child borrows your phone • Set your child's grade level, then move it up or back to grade 1 any time • A simple Free vs Subscribe chart, so you know exactly what you get

Start at your child's grade (subscription): take a short quiz or set the grade, and practice skips the earlier grades. Easy, Medium or Hard: pick how hard it is to earn play time, or set every value yourself. Try the yearly plan free for 7 days. Clearer parent settings: "Write to unlock" for apps opened by writing, "Always blocked" for apps that stay closed, and a status line at the top. Up to 50 apps in each list. On a phone set to Chinese, the app now opens in Chinese. The course now follows Taiwan's school character list, with Taiwan character forms and words.

Earn play time: every correct stroke adds seconds, every word adds minutes, and stars add more. At the end a clock winds up to the time earned. Tap Bonus to write an extra word for more time, or Exit to play. Parents set how many words to write, the time for each stroke each word and each star, a maximum per unlock, a daily bonus limit, and whether too little time keeps the app locked. Words now come up from the first levels. Stroke order and stroke shapes now match what Taiwan schools teach for over 1,200 more characters, including 艹, 辶, 阝, 戶 and 兌.

Lock & Learn now keeps selected apps locked until your child writes a character correctly. Parents can add their own study words, such as this week's spelling list, and practice will focus on exactly those words. This update also fixes an issue with Face ID.

• Opening the app from its icon shows a short poster, then the parent PIN. Writing starts only after a shielded app is opened and “Write to unlock” is tapped. • In Parent settings, the memory-write count is called Difficulty, from 1 to 5. • A challenge stays open for 15 minutes, plus extra minutes for each star. • “Hey Siri, turn on Lock and Learn” turns shields on. It does not turn them off. • While shields are on, Lock & Learn cannot be uninstalled. It can still be removed from the Home Screen.

The name is now Lock & Learn. • Points no longer stop Write to Unlock. The 100-point pause is gone. • Ticking a character on the Mastered list marks it passed, so learning continues with the next character. • Fixed B • Definitions, example phrases, and some character notes were corrected.

After free write-to-unlock pauses, open Lock N' Learn from its icon and enter the parent PIN to turn the shield off or delete the app. Pressing Start on a locked app still shows the subscription screen. From level 29, about one unlock in four asks for a short phrase made only of characters the user has already learned. The other unlocks stay one character. If the phrase is missed, the app asks for one character they already know, so it can still open.
