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.

I've been using primer for over a year. in the beginning, they gave redeem code for the points in exchange, but after the new update, they took the withdrawal option. but by adding the subscription, the withdrawal works fine and point reduction for every question is gone. Quite addictive and trustworthy app to use.

Primer has basically helped me a lot. I literally use it every day in school, on the bus, and I use it almost everywhere. The courses here are easy to understand and well-tailored for students to understand the concept. I recommend this app to every student out there, especially those who are homeschooling. 🤩

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.
