This one is our FAVORITE!
You can add your own words (Family NAMES, sight words, etc.) for your child to practice.
We recommend having your child practice with a stylus, to mimic holding a pencil.
The app is available for most tablets at a very low cost.
iPad only. You can only practice the letter groups together, not individual letters, etc. This is nice because it has the poems and has you practice the letters within their groups, but it is limited in how you can practice them.
