Heart Words Flash Card Game
Heart Words helps your child practice the high-frequency and irregular words that trip up early readers. Choose a word set, practice together as a family, and build reading confidence one card at a time.
Parent-led practice
An adult shows each card while your child reads aloud. You decide if they got it right — no screens in your kid's face.
5 minutes, real results
Short daily sessions build lasting habits. The app tracks streaks and marks words as mastered after 5 correct answers in a row.
