    Shameless plug if you want to practice your hexidecimal math https://matt-savvy.github.io/hex_math/

    I’m curious about this but the free strategies are the least interesting. And so I dropped off there.

    If you’re making money off the practice problems, why even gate the strategies?

    Just a thought. Love the site design though!

    You can look into any competition math site and get higher quality problems for free..

    A while back, I made something similar to this site's 'practice app', but bare bones:

    https://math.twilam.com/

    Just practice. No strategies. No config options. You just answer a set number of problems and you're done for the day. At the end of each session, you're told how long your daily streak is. No streak freezes. No login.

    My target audience is my 7yo son.
