Teacher developed app. Crabby Writer teaches early writing, reading, literacy and phonics for Preschool, Kindergarten, and first (1st) grade.

Our teacher-designed phonics and literacy game includes alphabet sounds (phonemes), rhyming words, themed words, spelling, proper letter formation, pincer-grip action, and a keep sake scrapbook designed to remind players of word meanings. It is fun to write in the sand, collect sea shells, and decorate sandcastles on our welcoming beach. Sand writing can now be at your child’s fingertips as we reinforce both phonics and rhyming structure. A literacy specialist who was among the first to try it out remarked, “What if learning to read had been this fun when we were young?”

It’s fun to learn to read and write on this beautiful beach, where waves wash from sea to sand, clearing a new surface for learning on phone-sized or tablet-sized devices.

Nicely Thought Out

I like this app for several reasons. While I as an adult with fingernails might not be crazy about the two finger touch necessary to work it, I really like this for students as it works to simulate the hand position necessary to write. I like the sizing of the seashells to indicate where to start the strokes necessary to make the letters and the phonetic pronunciation of the letter sound as each one is completed. It is also visually engaging and has enough animation to make it engaging without being distracting. The reward system of adding to the sand castle is also cute.

Nice app, but Juddly is annoying

I like this app for several reasons. I like that you have to form the letters in a certain order and that it gives the letter sound as you trace it. However, I have no intention of signing up for a Juddly account, but the app gives no way to turn off the notifications or to make it go away.


Fun Phonics & Finding Sandcastles!

My kids are learning phonics on the beach and sending me adorable emails from their game. I just checked my cellphone and found a sandcastle with our family name over the door. Love this game, and love hearing from my kids when they are with their sitter.
