★★★★★ Chilukuri Abhinay · Jul 3, 2025

It's very awesome, and it has Indian sign language and many accessible things that help me to understand fully what the words' mean. I go through barriers in my daily life like communication and I didn't know what words meant so Def helped me to be barrier free.😊⭐⭐⭐⭐⭐

★★★★★ raju Kamatkar · Mar 17, 2025

I'm grateful to the DEF ISL app for helping me improve my English skills. The app makes learning easy through Indian Sign Language. Thank you so much to the DEF ISL team - I don't have words to express my appreciation!

★★★★★ Dnyaneshwar Athargan · May 30, 2025

Whenever there's a communication barrier, people usually write or try to talk to us in English. I used to struggle to understand those sentences, but now things have changed. I just look up the word in the app, and it's that easy to learn something new!
