Publisher claims: "Use when setting up or fixing a home-office/desk workstation (new desk, new chair, aching neck/wrists by 3 PM, standing-desk height question) — computes your personal chair/monitor/desk numbers from body height with anthropometric proportions (seat 0.26H, desk 0.415H, seated eye 0.674H, standing elbow 0.63H), checks any monitor size for height/distance compliance, gives the laptop-compromise protocol (riser + external keyboard), maps your specific pain (neck/shoulder/wrist/eye/lower-back) to ranked likely causes with fixes, and prints the posture self-audit + 20-20-20 eye schedule."
