Textlexics has created a free Android app for children to learn and practice Arabic and English letters. The app is called "تعلم الحروف للاطفال بدون نت" which translates to "Learn Letters for Kids Without Internet" in English. It is an educational and reference app that helps children learn how to pronounce and write letters in both languages. The app is designed for children who are just starting to learn the alphabet and is suitable for children of all ages.

The app features a simple and easy-to-use interface that allows children to learn at their own pace. It includes the ability to draw letters in both Arabic and English, and also provides audio examples for proper pronunciation. However, the app does not currently include lowercase letters for English and does not support connected and unconnected Arabic letters.
