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.

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.

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!

This is an amazing app that helps simplify learning. The app has a ridiculous amount of topics. The quizzes are helpful for retaining the information you just learned. I'm sure a lesson or two a day will help you reach new height!!

It was really fun to learn about new topics everyday but 1)the earning feature was removed (which I'm pretty sure most of the users are here for) 2)accidentally deleted my app data so had to re login but guess what, instead of just getting access to my acc, the subscription screen is now here,can't log into my acc,no option to use the app for free(the scholarship should be in-app option really) So I guess this is the last day with Primer for me. I'd hate to see Primer turn into one of those apps
