FWIW my experiences with MathAcademy roughly overlap OP’s: it’s really hard work and adult life seriously interferes with making speedy progress (notice their own success stories are with teenagers who can devote hours upon hours on racing through the - very good - curriculum).
They say 1 point is equivalent to 1 minute of work and that you should earn at least 45 points a day. Well, for me 1 point is nowhere near 1 minute of work: I’m sloppy and sometimes downright stupid so it’s 1,5 minutes at best and often much, much more.
Banging your head against a wall every day for more than an hour (sometimes much more) just to get to what they consider to be the minimum of 45 points is no fun, and probably even counterproductive. I managed to keep it up for four months and made reasonable progress during that time (on getting back to where I was at the end of High School, 30 years ago) but it also burnt me out. I’ve now scaled it back to 30 minutes (not points!) a day. As a result my progress is now glacial.
Also, they’re very much of the “just do lots of problems and you’ll learn mathematic concepts and principles by osmosis” school of math instruction. For me I had to buy a textbook to get some extra explanation.
The good thing is that the problems seem well thought out and the spaced repetition system definitely works (for me, anyway).
I’m going to keep it up, because I have enough disposable income to afford it (though it is much too expensive for what it is) and I really want to bring my math skills up to a level where I can follow along the math in ML papers (and also because math, it turns out, is kind of elegant and interesting). I could go the self-study route, but then I’d have to spend time and effort guiding myself and figuring out what it is I needed to work on. If nothing else, MathAcademy is good at taking care of this for you so you can focus on the math itself.

Not a textbook, but https://betterexplained.com is an awesome resource for gaining intuition, its author's approach is very unlike others I've encountered.
I decided start with Calculus I on MathAcademy because that was the last thing I did in High School. MathAcademy disagreed and told me to do PreCalculus and even bits of Algebra II first, but I knew better (MathAcademy was right and in hindsight I should’ve just started the Foundation courses to build up my pretty weak algebra skills again).
For Calculus I simply use the textbook that’s recommended at the link above. As far as I can tell, it’s good. I don’t do the problems, though - for that I use MathAcademy.

I did a summer of khan academy over a decade ago.
I was switching from liberal arts to NLP and wanted to train my math muscle. I went with their “world of Math” which was a feature to go over all math problems “in order”. When stuck you could view the associated video.
I don’t think they have that feature anymore.
As khan Academy goes from preschool through high school, you start out by counting pictures of elephants and other exercises meant for young children to get comfortable with numbers, which was definitely too early a place to start.
I thought it was fun to see how such exercises looked and I didn’t really now how far I wanted to skip so I just powered through.
I think it was really good with the above caveat. My other two cents are: going from way too easy problems to problems you actually have to work on is jarring in terms of pacing. All in all I enjoyed it.
It’s love to know how it compares to MathAcademy. I think Khan Academy is of really high quality and to go from free to $50/month requires a lot of added value.

$49 seems a surprisingly high amount for something aimed at students and learners - I appreciate the content may be good, but it's effectively 3 times a Netflix subscription.
It's meant to be something you stick with in the "long term" by its nature, and yet an annual subscription is $500 - this is just completely unrealistic for any student. Someone in a lower end job hoping to "up skill" is going to really struggle with this.

The latest trend in educational software seems to be relatively high pricing. See e.g., Mentava, which sells for $500 USD/mo (not a typo). AoPS online courses are $28/lesson (though Beast Academy can be had for $100/yr). By comparison, this ($49) is in the realm of reasonable.
If this kind of pricing helps these services be sustainable over the long term, it's probably not a bad thing.

You can do that manually. Say for example you learn integration by trig sub today and you do 30 problems from a book. Next week you do some more trig sub problems.

But what I do know is millions of people have learned mathematics with books, pen and paper for hundreds of years.

I've recently gotten back into math and I'm really struggling with your approach. I find it particularly difficult to get an accurate view of how well I'm doing and where I am. Most concepts I ingest easily, and I demolish any exercises in the books I read, find on the internet, ask AI for, or scribble down myself randomly. I repeat them a couple of times to make sure. All is well. Cute green checkmarks abound. Categories marked as mastered. Pride bordering on arrogance. I move on. A week later I'm handed new concepts. The house of cards collapses. I haven't mastered any of the things. There are gaping holes in the information I was given and I wasn't knowledgeable enough to notice.
The author doesn't seem to share my difficulties either. His are of motivation and those seem to maybe be addressed by the resource he used and specifically sharing his progress with other users. For $50 I expect more than polished KhanAcademy, promises like "accelerates the learning process at 4X the speed of a traditional math class" (if anything I want to slow down), and a progress tracker to post pictures of on X. If I wanted to be told I'm amazing, how long my streak is, and to learn nothing I'd use duolingo.

Mostly sympathetic here, but your duolingo comment is a bit too harsh. Anecdotal counterpoint: my high-schooler used duolingo last summer to skip a year of instruction and get into AP Spanish as a junior, and got into the Spanish National Honors Society, and earned a fluency certificate. (I know most high school language classes churn out students who can't speak a lick, but her school is excellent and she has working fluency - which she credits largely to using duolingo to catch up.) IOW, YMMV.

What you describe is entirely normal in my experience learning lots of stuff and teaching many others. It might help you to let go of the idea that learning is a linear process where you master one topic and move on to the next. As I learn more I'm continually getting a deeper understanding of basic material I "mastered" decades ago. I often tell my students I don't think their understanding is complete but it is sufficient to move on, and the later material will help them get a better understanding. And it does!

When do you do exercises, do you refer back to sections in the book or examples? If so, this is a bad habit. Try to do exercises without looking back. This will force you to use your memory. Also don't be too quick to check solutions for things you're stuck on.
Everyone who does mathematics feels the way you do when learning something new. It's a normal feeling. Don't get disheartened. Push through it.

I used math academy for several months. I was curious and wanted to try it out since it’s a problem I’ve also worked on in the past. Th system is good, the fractional spaced repetition is a nice system and really reduces the spaced repetition overhead. Still IMHO, it provides nowhere near the value of the $50 a month pricing. But again I also know a lot of higher level mathematics and can work my way through a topology book on my own, so I’m probably not in the target audience. Still, I would think that even for people wanting to get into math or high school students this would still be a very steep price.

I'm at 10k points after a couple months. Previous experience was self-teaching linear algebra, which I needed for cryptography work, and I managed well enough to help my daughter cruise through a proofs-heavy linear algebra course at UIUC; I'd have aced it if I took it. I started doing MathAcademy for two reasons: to replace an NYT crossword habit with something more rewarding, and because I have (had) no calculus. I do about 250 points per week.
Math Academy is --- so far --- probably one of the better dollars-for-skills trades I've made in my adult life, easily outstripping every book I've ever bought.
I have a lot of gripes!
* The gamification is really annoying as an adult learner. There are lots of little cues in the system to keep moving forward, which pushes me past what feels like the limits of retention. There is no credential Math Academy can give me that I give a shit about, so moving faster for the sake of it is a bad trade for me.
* Along similar lines, I really wish it was easier to get more explicit review. Part of the premise of Math Academy is that the spaced repetition comes in large part from units that build on each other; you're making relentless forward progress with reviews baked into new material. I've at times had to have o4-mini make me problem sets, which seems dumb since I'm paying for exactly that from Math Academy.
* "Foundations", the adult learning series, is premised as being a curriculum stripped of stuff high school students learn solely because they'll be tested on it. They could strip it more. I got that sense in Foundations II but wasn't confident enough to call it out; now I'm doing linear algebra stuff and, I mean --- I object on moral grounds to inverting a matrix with determinants!
The flip side though: I have a decent grip on calc now, after just a couple months of doing this rather than crosswords. My trig, another weak spot, is annoyingly better (also I now know I authentically hate trig). The gripes are just gripes; my overall experience is, it does what it says on the tin.
I read people (and reviews, including expert reviews) complain about Math Academy's spartan approach to explanation/exposition/proofs. It's a super fair concern. For my part, I pair Math Academy with GPT; GPT is better than any online math education resource at explaining and handholding. I don't need explanations; what I need is a focused, structured curriculum: do this, then this, here's the problem sets, here's a graded quiz. I know how to read a book already; books didn't teach me any math --- university linear algebra course homework problem sets did. This is a better version of that.

> I object on moral grounds to inverting a matrix with determinants!
The determinant of a linear map is the induced effect it has on volumes. So it makes sense that it appears when inverting a map: if the forward map scales volumes by detA the the inverse needs to scale them by 1/detA. It also makes sense as an invertibility criterion: you can invert a map iff it didn't collapse the space down to a lower dimension iff it doesn't reduce volumes to 0.
Of course this is presented completely opaquely at a low level with the even more opaque cofactor matrix stuff.

I'm also on foundations 3 at this point and love the system. I combine it with Anki to reinforce the retention of older material, and I find the price very reasonable for something that helps me learn math consistently.
As for the price, I see people mentioning text books as a cheaper alternative, but Math Academy includes review work, tests, and retakes when necessary. It takes care of the organizing and evaluating that is related to but not the same as the learning. You can focus on being a student, without having to also be the teacher.
I would love a full depth, accredited system that didn't cost thousands of dollars.

I recently stopped my MathAcademy subscription: I went from halfway through Math Foundations II through to near the end of Linear Algebra. I stopped because I realised I wasn't really learning maths, I was just learning to answer the questions by rote.
The way that they pretty much completely omit all the explanation, proofs and discussion you get in traditional maths education really limits its utility once you get to more advanced content. I think the reason for a lot of the positive reviews is that their approach works really well early on when you're revising the basic end-of high-school stuff.

* Along similar lines, I really wish it was easier to get more explicit review. Part of the premise of Math Academy is that the spaced repetition comes in large part from units that build on each other; you're making relentless forward progress with reviews baked into new material. I've at times had to have o4-mini make me problem sets, which seems dumb since I'm paying for exactly that from Math Academy.
* "Foundations", the adult learning series, is premised as being a curriculum stripped of stuff high school students learn solely because they'll be tested on it. They could strip it more. I got that sense in Foundations II but wasn't confident enough to call it out; now I'm doing linear algebra stuff and, I mean --- I object on moral grounds to inverting a matrix with determinants!
The flip side though: I have a decent grip on calc now, after just a couple months of doing this rather than crosswords. My trig, another weak spot, is annoyingly better (also I now know I authentically hate trig). The gripes are just gripes; my overall experience is, it does what it says on the tin.
I read people (and reviews, including expert reviews) complain about Math Academy's spartan approach to explanation/exposition/proofs. It's a super fair concern. For my part, I pair Math Academy with GPT; GPT is better than any online math education resource at explaining and handholding. I don't need explanations; what I need is a focused, structured curriculum: do this, then this, here's the problem sets, here's a graded quiz. I know how to read a book already; books didn't teach me any math --- university linear algebra course homework problem sets did. This is a better version of that.
The determinant of a linear map is the induced effect it has on volumes. So it makes sense that it appears when inverting a map: if the forward map scales volumes by detA the the inverse needs to scale them by 1/detA. It also makes sense as an invertibility criterion: you can invert a map iff it didn't collapse the space down to a lower dimension iff it doesn't reduce volumes to 0.
Of course this is presented completely opaquely at a low level with the even more opaque cofactor matrix stuff.
As for the price, I see people mentioning text books as a cheaper alternative, but Math Academy includes review work, tests, and retakes when necessary. It takes care of the organizing and evaluating that is related to but not the same as the learning. You can focus on being a student, without having to also be the teacher.
I would love a full depth, accredited system that didn't cost thousands of dollars.
For those who really want to "learn math" as autodidacts, nothing comes close to the Open University textbooks that are freely available in your libraries and also with some clever searching online. That material is refined over decades to support the autodidact use case.
Since you created an account just to complain about this, do you have a rule for what people can or can't blog about? Do you only accept posts about OSS and free materials?
The way that they pretty much completely omit all the explanation, proofs and discussion you get in traditional maths education really limits its utility once you get to more advanced content. I think the reason for a lot of the positive reviews is that their approach works really well early on when you're revising the basic end-of high-school stuff.
But, when you don’t even focus on basic self-care, you sleep terribly, suffer depression, ADD, etc., you’ll never get past just browsing someone’s page of links to educational material to actually developing the habits you need to learn.
If someone could solve that, I’d pay them $50/mo.
If you want to actually learn mathematics, buy Open University book sets and work through them. MU123 -> MST124 -> MST125 -> M208 -> MST224. Diversion of M140 if you want stats. They are written by actual professionals, the course is accredited and if you like it you can turn that into an actual qualification as well. All the textbooks are in-house written over the space of over 40 years (!) and designed for self-learning.
The whole set is on github somewhere as well if I remember - search for it.
> Math Academy's courses are fully accredited by the Accrediting Commission for Schools, Western Association of Schools and Colleges. www.acswasc.org
OU are accredited by Institute of Mathematics and its Applications, Institute of Physics and Royal Statistical Society for example (I am a member of two of these).
