QuantQwik is the first iOS app built specifically for quantitative candidates, offering a complete set of cognitive, mental math, and problem-solving assessments inspired by the types of tests used in modern quantitative finance interviews. Candidates preparing for roles at firms like Jane Street, Optiver, IMC Trading, SIG, HRT, Citadel, and Two Sigma will find training that resembles the timing, pressure, and structure of real industry screens. QuantQwik brings together fast arithmetic drills, attention-control tasks, spatial reasoning challenges, memory tests, and risk-assessment mini games into one clean and polished platform. Unlike typical brain training apps, QuantQwik focuses on the exact cognitive skills that matter in quant interviews: speed, precision, numerical intuition, focus, working memory, and decision-making under uncertainty. Inside the app, users can practice a wide range of assessments. Mental math and numerical speed are trained through Quick Calc, 80 in 8, Percent Pro, Fraction Duel, and Number Sense. Attention and cognitive control are developed through Arrow Storm, Lightning Tap, and Spot the Switch. Memory and spatial reasoning are strengthened through Memory Matrix, 3D Mental Rotation, and Tower of Hanoi. Decision-making and risk evaluation are trained through Balloon Risk, which is inspired by behavioral assessment tools used in trading evaluations. The experience is designed to feel premium and focused. The interface uses smooth animations, refined typography, no ads, and intuitive visuals. All data is synced through iCloud, and the app is optimized for both iPhone and iPad. Performance metrics update as you train, showing accuracy, speed, streaks, reaction times, and personal bests for every assessment. Whether you are practicing for mental-math rounds, cognitive screens, or fast-paced numerical tasks, QuantQwik gives you structured preparation built around quant expectations. Free users have access to the essential assessments. A premium subscription unlocks all twelve assessments, the full statistics dashboard, custom practice reminders, and future premium features. QuantQwik is ideal for quant trading and research candidates, STEM students, competitive exam takers, and anyone who wants to improve cognitive performance in a measurable way. --- SUBSCRIPTION INFORMATION QuantQwik Premium offers two auto-renewing subscription options: • Monthly Subscription: Billed monthly, cancel anytime • Yearly Subscription: Billed annually, cancel anytime Subscription benefits include: • Access to all 12 premium assessments • Advanced performance analytics • Practice reminders and notifications • Full iCloud sync across devices Payment will be charged to your iTunes Account at confirmation of purchase.

I previously left a review about a bug within the game, and the developer team fixed it and notified me, too! Very professional. (I will be trying to delete that old review.) Whether you are looking to break into quant or just brighten your mind and be as sharp as a tack, QuantQwik is THE way to do it. **Developer response:** Hi Thank you for your review, please update the app, bug has been fixed. Kindly use the in app bug report feature to report any bugs. Thank you for using QuantQwik. Best Regards Shubham Tiwari ### 1/5 — Auto-Grader makes mistakes *2026-02-11* I’m not sure how this is even a bug, but the auto-grader will mark correct answers wrong often enough to be frustrating. Even the most simple -6 * 11 calculation was marked wrong. The answer is -66 but the auto-grader disagrees for some reason. ### 3/5 — Excellent content, not very responsive UI *2026-02-01* This is a nice app with very useful tools. However, the keys are not as rapid and responsive as you’d expect. It would nice to see improvements on input delay and responsiveness. Otherwise, excellent job on the content. **Developer response:** Hi Thank you for your review. Kindly use the in app bug report feature to report any bugs and please share a detailed suggestion regarding your request. Thank you for using QuantQwik.
