Blu makes the SAT's vocabulary finally stick. Instead of grinding a random 3,000-word list, Blu starts you on the 500 highest-yield words that actually move your score — the ones that show up again and again on the digital SAT — then expands as you master them. HOW IT WORKS - One lesson a day. 20 words, about three minutes: meet a few new ones, bring back what's due. No cramming, no guilt. - Two answers, no self-grading. "I know it" or "Not yet" — say Not yet and the card simply turns over so you can learn it properly. - Words in Context. Practice the exact skill the digital SAT tests — choosing the precise word for a sentence — with original, SAT-style questions. - Smart review. A spaced-repetition system brings each word back right before you'd forget it, so it sticks for test day. - Honest progress. Every session moves a real number: words learned out of the core 500, and out of the whole 2,814-word library. WHY BLU - The 500 core first: highest yield, least wasted effort. - Real example sentences plus clear definitions, etymology, and memory hooks for every word. - Audio pronunciation. - Calm, distraction-free design built for daily study. - Sign in with Apple once — your progress syncs across your devices and your subscription can never be lost. BLU PRO Free forever: the core 500 words, full audio, and one 20-word lesson a day. Blu Pro unlocks the 2,300+ word advanced library, unlimited daily lessons, 4x more AI explanations, and double streak freezes. Monthly or yearly, with a free trial on the annual plan. A few minutes a day is all it takes to make the SAT's words your own. Blu Pro is an auto-renewable subscription (monthly or yearly). Payment is charged to your Apple ID; it renews unless canceled at least 24 hours before the period ends. Manage or cancel in your App Store account settings.

The only daily limit is new words (5 core + 3 advanced tastes). • The level test is back: Me → Level test. Ten questions, your estimated score band, retake any time. • Cleaner question screens: bigger reading type, less clutter. • Words you miss on a check land in your notebook and come back early. ### 1.6.0 — 2026-08-28 Small groups, faster wins. • Your daily 20 words now come in four groups of five. Every group ends on a small win — and every group opens with words you probably know, never five strangers in a row. • A free taste of the advanced library: 3 advanced words every day, in your last group. What you start stays yours to review, and stays lit on the map. • Combo streaks: answer "I know it" a few times in a row and watch the ×3, ×4 build. It simply disappears when the run ends — no shame, no red. • The share card now speaks your language, and carries a QR code so a friend can scan straight to the App Store. • A nicer hello: the loading screen now teaches you one real word origin a day. ### 1.4.0 — 2026-08-26 A rebuilt Blu, designed around one idea: 20 words, about 3 minutes, every day. • Simpler cards. Two answers now — "I know it" or "Not yet". No self-grading, no red marks. Say "Not yet" and the card simply turns over so you can meet the word properly. • A Home that shows progress. Your core-500 count, your whole-library count, and what you added today — every session moves a number. • A clearer finish. Each session ends with what you gained: words met, words reinforced, your streak, and the bar creeping forward. • Bigger type, bolder buttons, and a map where the advanced half is always visible. • Reminders you choose. Pick your own time after a session — friendly, capped at two a day, never late at night. • Straight in. Sign in and you land on your first lesson; the old placement test and setup steps are gone. Fuller Simplified Chinese, Traditional Chinese and Japanese throughout. ### 1.3.0 — 2026-08-14 New: your Streak page! Tap the flame at the top of Home for a practice calendar, streak stats, and your progress toward the next milestone. Streak Freeze — miss a day and a freeze auto-protects your streak. Free members get 1; Blu Pro gets 2. Earn them as you practice. Plus a refreshed Home top bar and a cleaner, faster Pro screen. Thanks for using Blu! ### 1.2.1 — 2026-08-13 Blu now keeps your progress safely tied to your account. Sign in with Apple to start — your words, study plan, and streak sync across all your devices, and your Blu Pro subscription stays linked and restores automatically. Also in this update: • A cleaner, easier-to-scan Me tab • Fixed the Hard Words counter so the number always shows in full • Subscription reliability improvements Thanks for using Blu! ## More apps by Yuanwang Luo - [RunLang](https://appshunter.io/ios/app/runlang/id6757753633) - [投知卡](https://appshunter.io/ios/app/id6757800864) - [Tally Rule - Habit Tracker](https://appshunter.io/ios/app/tally-rule-habit-tracker/id6758990383) All apps by Yuanwang Luo: https://appshunter.io/developer/1868684859 ## Related topics [sat vocabulary](https://appshunter.io/ios/topics/sat-vocabulary) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
