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 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.

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.

The app is too good, and it boosts curiosity when learning subjects or taking up tests. I learned about Torque , and I enjoyed my time learning it, and questions are easy and not complex. The AI is good, and it selects topics to learn for me based on my score in my first test and the explanations it gave when I selected incorrect options is mind-blowing and I can learn from the explanations. I haven't seen an AI like this!!! Thank you, Primer...

I love using Primer Adaptive Learning. All the lessons and topics covered in this app are very useful for my studies. However, I would be even happier if the withdrawal option, like before, were available again.ā€

Unfortunately, the token conversion is now gone when I updated the app and it's disappointing because I just hoped I didn't update it. Previous version was so much better, you will be able to convert your token into money and withdraw it. This recent version is just not for me.

Thanks for sharing your feedback. Tokens were repurposed to support free users, but if you subscribe you’ll still be able to earn money through rewards and withdrawals.
