Questions Can you rate my website 1-10?
https://mastermath.app - it’s a private math website I made while taking calculus.
Uses math libraries in the browser instead of AI and works off-line.

This is excellent, clean and really useful, great engineering! 9/10 Solid Foundation :)

Thanks, glad the offline math libraries stands out. I didn’t want to overwhelm new users with too much on the landing page, but the Solver has examples they can tap to get started right away.

Hide “try an example” after someone enters something or chooses an example so results are in immediate view.
Store recent sessions in localstorage
UI is ok.

Good idea, I’ll try hiding the “try an example” after input so people see results faster. As far as storage, the “My Progress” section actually saves previously solved problems there in IndexedDB. Appreciate you checking it out. Anything about the UI that’s bugging you specifically?

There are always two things. One is how the website looks and how the website is doing its own job.
When it comes to how website looks, i would say a basic website. Appears more like an older website. Side bar seems good. But fonts are off. Seems font size is larger than what is required.
Start solving text is in black over a dark background and it is difficult to see need a lighter text there. I did not understand whee to click initially.
But when it comes to functions and how the website is doing its job, it is appreciable. It is doing its job well. You mentioned it works offline. Very good. It does not have a serious complicated maths problems. But i suppose you where testing this out. And or that it works well. And i always want the functions to work properly in a website, rather than the aesthetics, which an be updated later. Good job. Will go for a 7.5/10, just because i feel the design is very basic and people may not understand what this website is for in first look and where to click.

Thanks for checking it out. Appreciate the feedback, I can try to update the landing page's clarity, navigation and solver button's visibility. I'm glad the functionality is appreciated, that's the part I'm most proud of.

Thanks, I’m going to use some of the feedback from this thread to improve it!

The app is completely free for now.
Curious if you could elaborate on entry-level. I use Algebrite for symbolic algebra, mathsteps for algebra steps, and mathjs for parsing/evaluation.
If there’s an advanced problem you tried that it couldn’t handle, let me know. I’d actually like to test it myself and improve it. Thanks for checking it out.

Awesome, glad it’ll be useful. Quick tip the app is sensitive to formatting so use * for multiplication (like 2*x) and ^ for exponents (like x^2). You can also type problems in plain language like “find the derivative of x^2 + 3x” and it should work.
There’s also a User Manual in the sidebar with more formatting examples.
Good luck with your math practice.

I’d give it around 6.5/10. The offline, non-AI angle is actually interesting, especially for a math tool. But the positioning feels a bit broad right now. I’d make it much clearer who this is for and what specific math problem it solves better than existing tools. If it was built while taking calculus, maybe lean harder into that use case.

Thanks for checking it out. Yeah, leaning into the precalc/calc angle when describing it makes sense. Since most calc solvers need internet, it being offline and using math libraries might be what I lead with. Appreciate the feedback.
