The Institute of Human Anatomy's educational videos show you the why. Clarity provides the how.
Your body is not one number. It is a system.
Clarity by IOHA is a subscription-based lifestyle tracking and education app built to help you turn health knowledge into daily action. Developed with the Institute of Human Anatomy, Clarity helps you understand and support your body across five interconnected pillars: Diet & Nutrition, Exercise & Fitness, Sleep & Recovery, Mental Health & Cognitive Function, and Environment & External Inputs.
Clarity is designed for people who want more than a checklist. Every habit, task, and protocol connects back to the biological system it supports, so your daily follow-through becomes part of a larger picture. Nutrition habits feed your Diet pillar. Movement habits strengthen your Fitness pillar. Sleep routines support recovery. Your dashboard shows which areas are thriving, which need attention, and what to focus on next.
Access to Clarity’s app experience, including its guided protocols, AI Coach features, pillar-based insights, XP system, and rewards tools, requires an active subscription or other in-app purchase. Subscription options and pricing are shown in the app before purchase.
Follow IOHA Protocols
Clarity Protocols are curated bundles of habits and tasks developed by the IOHA team to support specific biological outcomes. Start a focused plan like Sleep Architecture Reset, Protein & Hydration Foundation, Cortisol Control Protocol, or Movement Minimum Protocol. Each protocol gives you simple daily actions, a clear time frame, and progress that connects back to your Pillar Health.
Ask Your AI Coach
The Clarity AI Coach helps explain the physiology behind your patterns, including topics like hormones, circadian timing, recovery debt, and nervous system load. Use it to better understand your health trends, create tasks, set recurring priorities, and identify the habit most likely to move the needle today.
Build Habits, Earn XP, Unlock Insight
Every completed habit earns XP for the pillar it strengthens. As you level up, Clarity makes consistency visible and can surface deeper context based on your recent progress. Your effort is no longer just a streak; it becomes a system you can understand, adjust, and build on.
Earn Points for Rewards You Actually Want
Clarity includes a customizable Rewards Shop where you can earn Points and redeem them for rewards you define yourself, such as rest days, new gear, IOHA content, or other milestones that motivate you. You choose the reward, set the price, and earn it through follow-through.
