About this app

Learn at your own pace from anywhere!

Primer is an educational app that includes lessons to help you learn about hundreds of important topics.

Primer uses an advanced adaptive learning algorithm to quickly identify your current knowledge and recommend new topics to study. After an initial assessment, you will be given lessons on useful topics that build on what you already know.

* Learn from anywhere in almost any language.
* Choose a curriculum for the subject you are most interested in studying.
* Adaptive learning decides when you are ready to move on to a new topic.
* Primer automatically reviews past topics to improve your long-term memory.
* Search from a library that covers hundreds of topics.

Primer is great for students just starting out, as well as adult learners who want to refresh their knowledge on specific topics.

Primer requires a subscription that can be purchased within the app. If you need financial support, you can apply for a scholarship in the app which will grant free access. We are committed to making learning accessible to everyone and your paid subscription directly contributes to scholarship access for others.

Note: This app is maintained by a small but dedicated international team. Please share your feedback and we will work hard to improve the app in future updates.

I have just started using this and the way the learning process are structured, it doesn't just teach you the concepts and helps you memorize it, but it also connects them together to encourage original thinking and curiosity. I have to say, so far, this is a game changer. If you're on the fence whether you want the app or not, do it—it is totally worth it!!!

This app is really great for students, and I introduced this app to my brother. Recently, he was really motivated by the reward system, and he did learn many topics and made notes of it. But this morning, after the update, he lost interest after knowing that the reward system was removed. Primer, please bring back the point and rewards withdrawal system. That really motivates the students. The older version and older interface were great.please consider the request.

Thanks for your feedback. While the earning feature was removed, we still offer quality educational content. This change helps us support more learners through a scholarship program for those who can't afford access. We hope you continue learning with us!

I’ve been using this app since last year, and the latest update made me a bit sad. It no longer allows access to free offline topics like before. I really hope you bring back offline learning so we can use it anytime, anywhere—especially during summer break. This app has great potential! Also, adding more images to the topics would be a big help for better understanding.

Thanks for the feedback! Offline access is still available—just open any topic from Topics section in Menu and tap the download icon to use it anytime. We appreciate your suggestion to add more images—great idea!
