Reading Den teaches your child to read the way reading specialists do — one sound at a time, in a carefully structured sequence, with nothing left to guesswork. Built on the science of reading, Reading Den uses explicit, systematic phonics: the approach with the strongest evidence for helping all children learn to read, especially those who struggle. WHY FAMILIES CHOOSE READING DEN • Personalized practice for confusing letters and sounds Mix up b and d? Short e and i? Reading Den notices the exact mistakes your child makes and gently brings those specific contrasts back into practice. Instead of simply saying “try again,” the app models the correct answer and guides your child forward. • Truly decodable stories Your child is never asked to read words they haven’t been taught to sound out. Every story uses only previously learned sounds and patterns, allowing beginning readers to genuinely decode every page — not memorize it. • One warm, consistent recorded voice Every sound, word, instruction, and story is professionally recorded, including isolated phonemes spoken clearly without extra “buh” or “duh” sounds that can make blending more difficult. • Encouraging correction — never punishment Wrong answers are met with a supportive “my turn, then your turn” approach, similar to working with a skilled tutor. No buzzers, timers, lives, or penalties. HOW IT WORKS Your child progresses through 43 worlds and more than 380 words, beginning with short vowels and continuing through digraphs, blends, magic-e, vowel teams, bossy-r patterns, multisyllabic words, and common word parts. Each new sound is taught explicitly: • what it looks like • what it says • how the mouth forms it Children then practice by building words, identifying sounds, and reading fully decodable stories. A short daily review brings mastered words back on a spaced schedule so decoding gradually becomes automatic and effortless. A quick placement check ensures your child starts at the right level instead of repeating skills they already know. FOR GROWN-UPS A parent dashboard shows skill progress, commonly confused letter pairs, and upcoming learning goals. Reading comfort settings include: • a dyslexia-friendly typeface option • adjustable text size • reduced motion settings Multiple reader profiles make it easy for the whole family to use the app. DESIGNED FOR STRUGGLING READERS Reading Den was designed around how struggling readers — including children with dyslexia — learn best: explicit instruction, continuous blending, cumulative review, and multisensory support. That same structure also makes it an excellent foundation for every beginning reader ages 4–8. PRIVATE BY DESIGN • No ads • No subscriptions • No accounts • No data collection Everything stays on your iPad, and the app works completely offline. One single purchase unlocks every world for every reader in your family. Start your child’s reading journey in the Den — where every word they learn truly becomes their own.
