TESTIMONIALS

See why thousands of learners, parents and teachers have already downloaded and love the app!

"Oppia has helped me see things I learn in real life with examples. I liked everything about Oppia. I also like the stories." - Jehdel, student

"I have always been shy at classes and I never answer my teacher because I do not like to make mistakes. Through Oppia, I feel more confident, because if I made mistakes, I have the chance to re-solve the question again, and to get the issue explained in multiple ways." - Seneen, student

"Bringing [Oppia] to the school is what will motivate the students. Students are not only supposed to learn around the 4 corners of the classroom; they are meant to learn from things they see every day. From what I saw by myself with Oppia, I can confirm this is so." - Mrs. Ndubisi, Mathematics teacher

“It feels good to find such content on the internet. I was worried about my children's education through this pandemic, these lessons are keeping my kids' minds sharp and active." - Jamal, parent

"I liked Oppia; I like the way the woman reads for me; I also like that it makes mathematics easier. I will tell others about Oppia so that mathematics can be easier for them as well." - Marvelous, student
