About AstroSpell
AstroSpell is a space-themed word mission game that turns spelling practice into a galaxy journey. Reveal astronomy words, manage oxygen, survive hazards, collect star coins, unlock achievements, and learn real space facts as you progress. The app includes campaign levels, a deterministic daily challenge, Spell-It recall mode, spoken word pronunciation, spaced-repetition review, accessibility-friendly typography, and a Mission Control learning hub. Version 1.3 adds Today's Flight Plan in Mission Control. The app reviews your local progress, missed words, review queue, and accuracy to recommend the best next session: Recovery Run, Spell-It, Campaign, or Daily Challenge. It also shows focus words, estimated practice time, and the category most worth reviewing. Core features include: - 200 astronomy word missions with original hints and facts. - Campaign, Daily Challenge, Spell-It, and Recovery Run modes. - Spoken pronunciation using on-device text-to-speech. - Spaced-repetition word review for missed words. - Mission Control learning hub with the new daily Flight Plan. - Difficulty profiles for different skill levels. - Achievements, star coins, upgrades, and galaxy map progression. - Safe offline play with local stats and progress. - Accessibility options including dyslexia-friendly typography. - Synthesized audio and haptics. AstroSpell does not require an account. Progress, settings, and word mastery stay on the device.
What’s new
Version 1.4 · Updated July 2, 2026
New in 1.4: the Star Codex — a browsable library of every word in the galaxy. Search and filter by category, revisit each discovered word's hint and science fact, check your mastery level, and hear any word pronounced or spelled out letter by letter. Plus new Practice Missions: launch a focused five-word recall session on any category, built automatically from the words you find hardest. Also fixes a small button-label wrapping issue during missions.
