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.

The app doesn't have any real progression system. The learning process is reading a condensed article on a topic and then answering 5 questions about it, then moving on. There's no knowledge review system. Some of the questions can be answered by pure intuition, too. The app seems to have full AI integration, so that's a good thing for its future if it's worked on. The app does have a paywall, but the scholarship option gives you free access if your budget is tight. Please work on it, devs.

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.

Good so far. I'm enjoying learning using it, though I haven't used it long enough to find any faults yet, but in grateful that it's free and has no ads. The AI is very useful and it makes it fun to learn
