While it was created to serve adults, 26 Letters is visually-designed for learners of all ages: LEARN LETTER SHAPES Practice writing upper and lowercase letters on-screen with your finger or stylus. A moving hand guides the direction to correctly trace each letter.

PRACTICE WITH EVERYDAY WORDS An additional 150+ images of everyday words to practice listening for first, middle and last sounds. Images are accompanied by audio – perfect for beginner English speakers to learn simple words while learning to read. VISUALLY-FOCUSED Friendly images, video tutorials and clear icons make it simple for the non/beginner reader to understand and navigate. FREE & EASY 100% cost and ad-free. Easy and fun to use.
