Join millions of families and download Wonster Words today! _______________________ 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." _______________________ FITS YOUR NEEDS Wonster Words supports offline play when traveling. It is safe for kids and ad-free.

Verdict

The call

The clearest difference is price: Wonster Words Learning Games at Free against Speech Tutor Pro's $69.99. Wonster Words Learning Games also leads on rating (4.6 vs 4.3) and ratings volume (32K vs 83). Speech Tutor Pro's advantage is in-app purchases (none vs 16) and iOS requirement (12.0 vs 15.0). On review sentiment, update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Wonster Words Learning Games holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Wonster Words Learning Games has 32K ratings behind it against 83, so its average is the more settled of the two. Written reviews complicate that: 82% of Wonster Words Learning Games's written reviews are positive against 85% of Speech Tutor Pro's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Wonster Words Learning Games ships an update every 3 weeks, Speech Tutor Pro monthly. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
