Blu - SAT Vocab

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.
