Remember every Chinese character you learn. Most apps ask you to recognize characters. Skritter asks you to write them, because writing is one of the fastest ways to make a character stick. When you write a character, you recall every part of it, so the next time you see it, you really know it. Self-studying or taking classes? Learn Mandarin with HSK, TOCFL and textbook vocab, in simplified or traditional characters. WRITE TO REMEMBER Recall each character stroke by stroke, with instant feedback on your handwriting and stroke order. Prefer to focus on readings and meanings? You can turn writing off any time. SPACED REPETITION THAT FITS YOUR DAY Our spaced repetition system (SRS) brings each word back just before you forget it, so you practice what is slipping and skip what you know. Daily reminders keep the habit going, and a few minutes a day adds up to thousands of characters over time. HSK, TOCFL AND YOUR TEXTBOOK - HSK 3.0 levels 1 to 3, with more levels added as they are released - Every HSK 2.0 level - TOCFL decks - Most popular Chinese textbook series, chapter by chapter, so you can study this week's words tonight 700+ DECKS AND GUIDED COURSES - The Skritter Character Course: learn how characters work and master 150 high-use characters - 100 Common Radicals: see how characters are built - Chinese Stroke Order: eight simple rules for balanced, readable handwriting - Hundreds more topics, with new video lessons added regularly - Or build your own word list in seconds.

Verdict
The clearest difference is in-app purchases: Modu at none against Skritter's 10. Modu also leads on update cadence (weekly vs every 5 weeks). On price, ads, device support and iOS requirement there is nothing between them.
