Frederick works like a puzzle, letting users understand the rules of reading, spelling and pronunciation without needing a parent or teacher, following any instructions, or studying any rules.

Say goodbye to waiting for tutors, confusing interfaces, goofy gimmicks, boring exercises, instruction prompts and translations. Frederick keeps only what learners need to have fun, and become confident readers and spellers as fast as they like.

Learners can follow the whole program in easy steps - or focus on particular sounds and words - then test themselves to prove they understand lessons. Games and video game mechanics also ensure learners can't force their way through the app. So when you beat levels, you KNOW you've improved.

From "A" to "apocalypse," master over 2,000 words and sentences all in one app! Frederick's 35 levels cover various spellings of the 44 sounds of English, as well as the most common words that BREAK pronunciation and spelling rules. Develop listening comprehension, build a large vocabulary, learn grammar intuitively, and gain confidence in all communication skills.

Frederick can complement traditional instruction in schools, serve as a complete reading curriculum and learning method for homeschoolers, provide scalable adult literacy instruction, teach adult English language learners pronunciation and spelling, and help immigrant speakers of ANY language learn English easily. Even learners with reading disorders like dyslexia can improve with Frederick.
