I built Mutorials because studying science often feels passive and inefficient.

It is a simple training app for physics, chemistry, biology, and earth science. You choose a subject and start practicing right away. The app gives you questions matched to your level, and every answer comes with a clear explanation so you can understand what you missed.

As you get questions right, you earn rating points and the difficulty increases. You can actually see your progress as it happens, which makes it feel more like a game than studying.

There are also full reference sheets for each subject if you want to review concepts quickly, plus a leaderboard to compare progress with other learners. We also have a Discord where people help each other out.

The whole thing is free. No ads, no subscriptions. Just trying to make a tool that helps people get better at STEM.

Would really appreciate any feedback.
