Wordglow

Vocabulary test prep for grades 6–12. Free, offline, and private by design.

What it does

Wordglow teaches the vocabulary that shows up on the SAT, ACT, PSAT, ISEE, SSAT, SHSAT, and state assessments — using spaced repetition, so each word comes back right before it would be forgotten. Sessions are short, kids can stop at any time and keep what they earned, and a PIN-protected parent area shows how it's going.

Private by design

• No accounts, no sign-in, no ads, no tracking
• No network requests — the app works entirely offline
• All progress stays on the device, and parents can export a copy any time
