HanziPop vs SpeedMath

HanziPop teaches you Chinese in the moments you're already looking at your phone — on your Lock Screen, in a Home Screen widget, and in a daily notification. No streak guilt, no 20-minute lesson required. — WHAT YOU SEE EVERY DAY — A single hanzi with pinyin and meaning, picked from your active queue. Tap to mark it known, hard, or skip to the next one. The next time you glance at your phone, a new word is waiting. — WHAT'S INSIDE — • 10,000+ words across HSK 1-7 • 1,000+ structured lessons • 12 themed packs (Food, Travel, Work, Family, and more) • Native-quality pronunciation (Apple TTS) • Example sentences with pinyin and English • Favorites, lesson history, and a progress ring — HOW IT LEARNS YOU — HanziPop uses FSRS, the modern open-source spaced-repetition algorithm that schedules each word based on how well YOU remember it. Words you find easy show up rarely. Words you stumble on come back sooner. — PRIVACY-FIRST — • No account, no sign-up • No tracking, no ads • Your progress syncs across your devices through your private iCloud — Apple holds the keys, not us. We never see your data. — FREE & PRO — Start free with daily new words from HSK 1-3 and 3 themed packs. HanziPop Pro unlocks the full HSK 1-7 library, all 12 themes, unlimited daily words, and advanced widget configurations. — BUILT FOR THE LOCK SCREEN ERA — Most Chinese apps want you inside the app. HanziPop is built around the truth that you'll learn more if Chinese is just there, every time you pick up your phone. Two seconds, a hundred times a day, adds up faster than one 20-minute session you keep skipping. Built by an indie team that uses HanziPop every single day. We answer email.

SpeedMath is math practice that adapts to you — 1,500 levels running from Grade 1 all the way through Expert, with no two people starting in the same place. A short adaptive placement quiz figures out exactly where you belong the moment you open the app: get a question right and it gets harder, miss one and it gets easier, so you're never stuck redoing what you already know or lost on what you don't. Two ways to answer: - Type mode: a custom keypad built for speed, with a scientific "Pro" calculator for exponents at the advanced levels - Speed mode: just say your answer out loud and keep moving Stuck on a problem? Hit "I don't know" and get a plain-language explanation that actually clicks, pitched to your exact level, not some generic textbook page. Every correct answer builds your streak. Every session pushes your daily goal forward. And the level ladder never runs out — grade-school arithmetic, pre-algebra, trigonometry, calculus, and all the way into university-level and expert problems. Free to start, with a generous placement-based trial. Upgrade any time to keep climbing every one of the 1,500 levels.
