Sentenceglow: Grammar Practice

Eleven grammar skills, 800+ questions, every miss explained. Questions come back right before they'd be forgotten. Free, offline, and completely private.

Help your kid stop making the same grammar mistake twice.

Sentenceglow teaches the grammar that shows up on school writing and standardized tests — subject-verb agreement, who and whom, commas and semicolons, verb tenses, misplaced modifiers, parallel structure, capitalization, commonly confused words — using spaced repetition, the same science behind the most effective study tools. Every question a kid misses comes back the next day, then right before it would be forgotten, until it sticks. Every answer, right or wrong, comes with a short explanation of why.

Questions match your kid's grade. A sixth grader starts with the basics; a high schooler skips straight to the tricky ones. Older kids meet the easier questions later, never lose them. And the daily goal is a pace, not a cap: a kid on a roll can keep going as long as they like.

827 questions across eleven skills and five difficulty tiers, all hand-checked, from the makers of Wordglow.

FOR KIDS (GRADES 6-12) • Short daily rounds: reviews first, then today's new questions, then bonus practice • Tap an answer, learn why, move on — stop any time and keep everything you earned • XP, levels, streaks, and badges that reward effort — a miss still earns points • A mastery ring for every skill, so progress is visible • Pick a goal to work toward and watch it fill up on the home screen

FOR FAMILIES • Set each kid's grade and a daily goal; nudge the difficulty gentler or harder • Parent dashboard: streaks, minutes practiced, accuracy week over week, the skills that need the most work, and the questions your kid keeps missing • Reward deals: your kid proposes "practice 7 days in a row → movie night", you approve it in PIN-protected parent mode, and the app tracks it honestly • Multiple kid profiles on one device • Export a full backup or a spreadsheet of answer history any time

PRIVATE BY DESIGN • No accounts, no sign-in, no ads, no tracking • No internet needed — the app makes no network requests at all • Everything stays on your device. We collect nothing.

Free, with no in-app purchases.
