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 from the app. now, the points we store are of no use and there is no motivation to keep on going other than learning. after the new update, daily quest +5 points are also in a glitch. It shows in the quest the reward is sent but in the transaction list it isn't. only the daily login points +10 is available.Don't install nouse at all

Thank you for your feedback! The withdrawal option remains available after purchasing a subscription. Regarding the daily quest, please make sure that the completed topic is a new one — tokens are only awarded for new completions. Repeating previously completed topics won’t count toward the daily quest.

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. 🤩

I love this app,It helps me with my knowledge and learning things faster.. But I wish that there would be different explanations for each question in the test where they select which topic you should learn.Like I picked an answer-its right.And there is a small explanation on how the answer is correct,I mean I don't have to type again.
