_______________________
A FUN, PLAY-BASED APPROACH TO LEARNING
Children learn best when they’re having fun! Wonster Words combines interactive phonics puzzles with engaging animations to make reading feel like play. Kids explore words by dragging letters into place, hearing their letter names and sounds, and watching hilarious animated shorts that bring vocabulary to life.
• "As a 1st grade teacher with a kindergartener [son] I know how important it is to keep learning interesting. This is my son's favorite app and mine too."
• "I downloaded this game for my 2 yr old daughter and she is always running off with my phone to learn some new words."
_______________________
BASED ON THE SCIENCE OF READING
Wonster Words is built around phonics-based learning, research-backed principles that support early reading success. Kids go beyond basic ABCs and phonics—they learn how letters form blends, digraphs, word families, diphthongs, and CVC words, all key building blocks for fluency.
• "This app really helps reinforce the phonics principles and sight words we go over daily. I love that my children are eager to learn and have fun doing it."
• "[My 5 year old] has been using Wonster Words each night and has started to spell on his own. We are sounding out words together. He looks forward to playing the games and even reminds me of his practice time.
_______________________
CUSTOM WORD LISTS & SPELLING LESSONS
Every child learns differently, and now you can personalize their learning experience! With our Custom Word List feature, parents and teachers can enter their own words, and Wonster Words will automatically generate phonics-based spelling lessons tailored to those words.
• "I love this for my child’s spelling words. I am able to add our own words for her to practice and she enjoys the games."
• "Wonster words spelling has been a big help for my 3rd grader prepping for weekly spelling tests at school."
_______________________
SUPPORTS SPEECH & LANGUAGE DEVELOPMENT
For children with speech delays or language difficulties, Wonster Words provides a fun and effective way to practice articulation, phonological awareness, and vocabulary building. It’s an excellent supplement for speech therapy and a motivator for kids working on communication skills.
• "My three year old was slow to articulate many words. Speech therapy was helpful but he seemed bored with the simplistic repetitions. Got this game to work with him at home... He's four now and still loves this app. Non-stop chatterbox with a huge vocabulary."
• "I am a retired Speech-language Pathologist and I provide training for preschools. I love this app for vocabulary building, early reading and spelling."
