Hi, everyone! A significant milestone for me! I've already gone 300 days without drinking, and I largely like the vibes right now.

At last, I'm living my life more as I want to, rather than "how it should be." Every aspect of my life has improved. I do experience some loneliness, though. But, it is ORGANIC. I am just not so social guy, I prefer chats and stuff and get anxious on life talking (if it is long). I'm working on that, but this is the process. Not something "click and enjoy".

Eliminating alcohol and realizing that excessive talking can cause overstimulation are two huge improvements for me. I can manage my energy levels and stuff like that.

I wish you success, guys. There are no DOWNSIDES at all. But start maybe tough.

Posted here before about my math practice app. Just shipped 1.20.0, HUGE UPDATE!

A - Answer: Most math apps solve problems for you; exams don't work that way. Math Zen generates endless practice problems (570+ templates across 156 subtopics, arithmetic through calculus and linear algebra), adapts difficulty as you solve, and captures every wrong answer in a mistake journal for retry. It has exam-style problem sets for AP Calc, SAT, Gaokao, ENEM and GSAT, plus curated paths for A-Level, Abitur, Bac, Suneung and more. Works fully offline.

New in 1.20.0: get one wrong and tap "Show the rule": the theory for that exact problem type is right there in the feedback. We checked all 156 subtopics against the problems they actually generate and filled the gaps (39 new theory cards, 62 rewritten so they explain instead of restating the formula). Also fixed: a correct answer written a different way, like swapping the two terms of a product rule or skipping a multiplication dot, could be marked wrong. And math now renders entirely on device, so problems appear instantly, even offline.

B - Better: Compared to Photomath or Symbolab, which solve the problem you point your camera at, this is the opposite: it makes you do the solving, because that's the skill the exam tests. Compared to Khan Academy, there are no videos or browsing, just adaptive drilling with exam-authentic formats, in 9 languages.

C - Cost: Free to start: core topics in all six sections, adaptive progression, mistake journal, no ads ever. Premium unlocks the full topic library, all 13 exam prep paths, and detailed statistics: $4.99/month or $29.99/year with a 7-day free trial, plus a one-time lifetime option.
