Posture Max: Fix Your Posture, Evolve Your Shrimp Meet your new posture coach — a tiny shrimp who lives in your phone and evolves as your back gets stronger. Posture Max turns the boring grind of fixing your posture into something you'll actually want to do every day. You start as a curled-up shrimp on a tail coil (relatable). Build better habits and your shrimp evolves through 5 stages — eventually transforming into a fully upright, golden-crowned, armored shellbeing. Yes, really. ▸ AIRPODS POSTURE MONITORING Your AirPods Pro, AirPods Max, or AirPods 3 already have motion sensors. We use them to catch you slouching in real time — at your desk, on the couch, mid-doomscroll. Every hour of good posture earns XP for your shrimp. ▸ AI POSTURE SCANS (a.k.a. Shell Reports) Snap a quick photo and your AI coach generates a Shell Report: a 0–100 shell score, the exact zones letting you down (hello, forward head), and a set of training drills built for your body. Each scan earns XP. Improvement vs. your last scan earns bonus XP. ▸ EVOLVE YOUR SHRIMP THROUGH 5 STAGES Stage 1 starts curled and tired. By Stage 5, your shrimp is fully upright with a golden crown. Every check-in, drill, scan, and good-posture hour pushes you closer to the next evolution. The progress bar is real. The dopamine is real. ▸ TRAINING DRILLS THAT ACTUALLY GET DONE Targeted stretches and strength drills for your specific weak zones — chin tucks, wall angels, shoulder rolls. Each one takes a minute or two. Each one earns XP. Your shrimp watches. ▸ STREAKS, NUDGES, AND DAILY CHECK-INS Friendly nudges from your shrimp keep you accountable without nagging. Build a streak and your shrimp gets brighter, happier, more alert. Break it and… well, your shrimp will be sad. But forgiving. ▸ AI POSTURE COACH IN YOUR POCKET Ask anything. Get personalized exercise plans, ergonomic advice, and answers to your weirdest posture questions. Like a physical therapist, but one that lives in a coral garden. ▸ BUILT FOR • Desk workers, remote workers, and office professionals • Students and gamers • Anyone with neck or back discomfort • Fitness people who care about alignment • Anyone who wants a tiny crustacean to hold them accountable ▸ PRIVACY FIRST Posture photos are analyzed but never stored permanently. Your data syncs securely when you sign in, and you can delete everything anytime. SUBSCRIPTION INFO Posture Max offers a premium subscription that unlocks unlimited shell scans, full AI coaching, all training drills, and the full evolution journey. • Payment is charged to your Apple ID at confirmation of purchase • Subscription auto-renews unless canceled at least 24 hours before the end of the current period • Manage or cancel anytime in your App Store account settings Terms of Use: https://www.posturemaxapp.com/terms.html Privacy Policy: https://www.posturemaxapp.com/privacy.html Your posture shapes how you feel, how you look, and how you age.
