If you're on android check out the puzzle suite app on fdroid
If you like geometry and trig, the apps Pythagorea and Euclidea are very fun puzzles. They're free and there are hundreds of puzzles. They get very difficult.
If you like doing long paper working, a youtube channel called mind your decisions has a vast wealth of problems. Some of them are duplicates with different variables. If you turn on youtube history you can effectiveky mark off how many you have solved.
I think scientific american has short maths and logic puzzles publiahed maybe weekly or daily. https://www.scientificamerican.com/games/math-puzzles/
Also shout out to cryptogram/cipher style games, which i see as reasonably mathematical

I think the puzzle baron one might be dominated by bots because it has solve times of 1 second listed when i do it.
The app Mental Math actually improved my mental math indeed! While division can typically be estimated because it never goes into mixed numbers/fractions, it does eventually go into 5 digits' worth of all the 4 basic operations; you set the difficulty and climb as you like. I'd never multiplied so accurately in my life, haha.
i like simple math, i love this app. just cruise through; even has tutorials for tricks and stuff.
its called FastMath
