Words are forged, not memorized. Reading Forge turns learning to read into a warm fantasy craft game. Your child is an apprentice smith, and every phonics skill they master lets them shape letters, sounds, and words into artifacts, tools, and stories. It's explicit, structured-literacy instruction, inspired by the Orton-Gillingham approach, built for beginning readers, kids with dyslexia, tutors, and homeschoolers. WHY FAMILIES CHOOSE IT - Decoding, not memorizing: kids build words from sounds, so they can read words they've never seen. - Multisensory: see it, hear it, say it, and write it with finger or Apple Pencil. - Calm and kind: no ads, no punishing timers, no red X's. - Works offline, on-device. Nothing about your child leaves the iPad. - Starts at the right level with a short placement trial and tracks every skill. A COMPLETE READING JOURNEY Ten regions of the Smithing Lands take kids from first letter sounds and short vowels, through digraphs, blends, magic e, vowel teams, and r-controlled vowels, all the way to syllables and word parts - roughly Pre-K through grade 4, one skill at a time. PLAY THAT TEACHES Build Words, Vowel Valley, Write It, Sound Boxes, Word Chains, and more, plus a Story Vault of decodable readers unlocked as kids progress. FOR GROWN-UPS A parental-gated Guild Office with progress reports, assignments, and a recording booth to use a familiar voice for sounds and words. FREE TO START The first regions - letters, short vowels, and blends - are free forever. A subscription unlocks the full curriculum: $4.99/month or $39.99/year, with a 7-day free trial. Subscriptions renew automatically; manage or cancel anytime in your Apple account settings. Reading Forge is inspired by the Orton-Gillingham approach to structured literacy. It is not an Orton-Gillingham certified or affiliated program. Reading Forge Full Access — auto-renewing subscription. Unlocks all 10 lands and every practice game. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless canceled at least 24 hours before the end of the current period.
