Built by people who hated studying.
We built Octagon for students who can spend ten hours inside a video game but struggle to spend ten minutes inside a textbook. Games are designed to be fun. Most study apps are designed to look thorough on a parent's dashboard. That gap is the problem we set out to close.
Why we built this.
We started with a simple observation: students will pour entire weekends into a video game they'll forget about in a month, but struggle to sit with a single chapter of physics that could shape their career. Games are engineered to bring you back tomorrow. Most homework apps are engineered to look thorough on a parent's review page. The gap between those two design goals is the problem we set out to fix.
Most education tools treat effort like a punishment. You log in, slog through it, get a grade, and log out feeling slightly worse than when you started. There's no reward loop, no real feedback, no reason to come back the next day other than guilt. Games figured out how to make repetition feel rewarding in the 1980s and have been refining it ever since. Nobody had seriously tried to apply those same principles to the actual work of learning.
Octagon is our attempt to do that, properly. The content stays exactly what it should be — Algebra is still Algebra, Chemistry is still Chemistry. What changes is everything around it. Streaks. Weekly leagues. Twelve belts to earn. Six distinct game modes. A question bank in the six figures, with every item reviewed by humans before it ships. And a teacher avatar who walks you through the lesson before you head into practice. Free to start, free to climb.
What actually matters to us.
Make studying feel like a video game.
Games are engineered to bring people back tomorrow. Study apps, mostly, aren't. We took the mechanics that actually work — streaks, leaderboards, the small reward when you land a perfect round — and applied them, properly, to practice problems. That's the whole product.
Short lessons, then practice.
No 80-page textbook chapters. Lessons are slide-sized — two teacher avatars walking you through the concept, with try-it questions built into the flow — and then you head into practice. Anything you miss is reviewed before you move on.
Something is actually on the line.
Each Monday you're matched with around 30 students who put in roughly the same effort you did last week. Top 5 promote a tier. Bottom 5 drop one. Add friends if you'd like, but plenty of users climb on their own just to see how far they can get.
Just a few of us.
We're a small team — a handful of engineers, an experienced classroom teacher who keeps the curriculum honest, and a few content writers and reviewers building and auditing the question bank. We spend a lot of time arguing about what separates practice that feels rewardingfrom practice that feels like a worksheet. We're hiring deliberately.

Common questions.
Who is Octagon for?▸
Primarily middle school through college students. If you're studying for the SAT, an AP exam, a calculus final, or you just want to stay ahead in class without losing focus, the app is built for you.
Is it free?▸
Yes — the core app is free, including lessons, weekly leagues, and every game mode. A paid tier is available for students who want unlimited Sprint sessions and deeper progress analytics, but it isn't required to learn the material.
How are questions made?▸
Every question is written in batches and reviewed by humans before it ships. Each one lives in a curated question bank that the app pulls from at runtime — nothing is generated on the fly. Each item is tagged by difficulty so the app can match what you see to your current level.
Where is it available?▸
Coming soon to the App Store and Google Play. We're currently in closed beta. Sign up on the homepage and we'll send you a TestFlight invite when a slot opens up.
