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!!!

It is very disheartening to know that the application has become completely paid now. Earlier, we could gain a lot of information on any topic and clear our doubts all for free, then once, the token system was introduced. And know, the app is completely paid which is extremely bad and sorrowful as well. Educational apps should be made free id partially free, not completely paid. 💔

We understand your concern. While the app now has subscription plans, we also offer a scholarship program for students who can’t afford it. This way, eligible users can still access learning resources for free. Thanks for the feedback!

The app is great, it's just like a real-life scenario of knowledge accumulation. The app helps to enhance knowledge, and gain understanding. It is very easy to use, and what makes it even more fascinating are the questions that are asked, helping you to gain a deeper and broader understanding of the studies; even the way the questions are structured is another amazing aspect of the app. I truly love it.
