BRAIN! vs RunForm 3D

BRAIN! is an app that helps you evaluate and track your brain’s condition. When you’re struggling to concentrate or feeling mentally foggy, BRAIN! allows you to quantify your cognitive state. It measures four key indicators: ・Focus (SART) ・Cognitive control (Stroop task) ・Working memory (n-back task) ・Processing speed (TMT) Easy to use — each test takes less than 5 minutes. Your scores are automatically saved and visualized in graphs to track changes over time. Ideal for checking your mental condition before and after work or study, or monitoring the effects of sleep and nutrition. Also great for peak performance and recovery planning. Your brain deserves conditioning, too. Start visualizing your cognitive power with BRAIN!

RunForm 3D analyzes your running form using monocular 3D pose estimation — just film yourself from the side with your iPhone. - Automatic ground-contact detection - Key determinants of running economy: cadence, vertical oscillation, ground contact time and more - Per-factor good / acceptable / needs-improvement zones - Form Efficiency Score (0-100, an estimated proxy) with a confidence label How to use: enter your height (optionally target pace), fix your phone and film from the side so the whole body fits, run a few steps, then stop to analyze. Important: The app interface is in Japanese. Scores and metrics are estimates derived from motion, NOT direct measurements of oxygen uptake (VO2) or running economy.
