Quantify is a mobile app that teaches quantitative finance in short, gamified lessons — probability, statistics, stochastic calculus, options, market microstructure, algorithmic trading, C++ for HFT, and more. Each lesson is a stack of quick cards with concepts, code, and quizzes. It's built to fit in five minutes.
Yes. You can learn for free with a daily lesson in every track, plus streaks, XP, achievements, and the leaderboard. Quantify Pro unlocks unlimited lessons, the full spaced-review engine, and every track — for $4.99/month.
Quantify Pro is billed by Apple. To cancel: open your iPhone Settings → [your name] → Subscriptions → Quantify, then cancel. Your Pro access continues until the end of the current billing period. Deleting the app does not cancel the subscription.
Open the app, go to Profile, and tap Restore Purchases. Make sure you're signed in with the same Apple ID you purchased with. If it still doesn't unlock, email us and include your account email — we'll sort it out.
Purchases are handled by Apple, so refunds go through Apple. Visit reportaproblem.apple.com, sign in, and request a refund for Quantify. If you think you were charged in error, email us and we'll help.
Streaks reset if a day passes without completing a lesson. Set your daily reminder for a time you'll remember (Onboarding or Profile settings). If a streak was lost due to a genuine app bug, contact support with the date and we'll take a look.
Check that notifications are allowed: iPhone Settings → Quantify → Notifications. Then confirm your reminder time inside the app. If notifications are on and still silent, restart the app once so it can re-register your device.
On the sign-in screen, tap Forgot password and enter your email. You'll get a reset link. If you signed up with Apple or Google, use that same button to sign in — there's no separate password to reset.
Go to Profile and edit your username or tap your photo to pick a new one. Your name and photo appear on the leaderboard.
Open Profile → account settings → Delete account. This permanently removes your profile, progress, and associated data. The action can't be undone. See our Privacy Policy for details on what's deleted.
Not yet — Quantify is currently iOS only. An Android version is on the roadmap. Want to be told when it lands? Email us and we'll add you to the list.
No. Quantify is educational. The lessons teach the math and mechanics behind markets, but nothing in the app is financial, investment, or trading advice. See our Terms of Service.
