About CornerIQ
CornerIQ is made for boxers, by a boxer. The goal is simple: help close the gap between athletes who already have access to coaches, strength and conditioning support, nutrition guidance, and structured planning, and the boxers who are still building that team around them. CornerIQ does not replace a boxing coach, S&C coach, nutritionist, doctor, or qualified professional. It is here to support the athletes who do not have all of that around them yet, so training can be more organized, more conservative, and safer while they keep building. Built for boxing, not generic fitness: - Set up your boxing profile and fixed weekly boxing sessions - Check today's readiness from manual logs like sleep, energy, soreness, stress, mood, hydration, food, and body weight - Review support training around coach or team boxing work - See fuel and hydration prompts that stay conservative when context is incomplete - Track plan adjustments, unavailable days, deload requests, and next-week training context - Export or delete app data from Profile Manual input is first-class. CornerIQ does not require a wearable. Wearable signals, when available, are treated as extra context rather than the source of truth. Safety boundaries are part of the product. CornerIQ does not provide medical diagnosis, emergency support, fertility prediction, generated sparring, contact drills, fight simulation, or unsafe weight-cut instructions. Missing data remains unknown, not safe, so the app may show conservative guidance when fuel, hydration, weight, or safety context is incomplete. CornerIQ requires an account. Sign-in and onboarding are available before purchase. Product features are available with CornerIQ Pro after onboarding, and restore purchase, privacy, support, export, sign out, and delete-account controls remain available without purchase.
