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.

Bad posture can make anyone look shorter, smaller, and less confident than they actually are. PostureMaxx helps you identify a starting focus and work on it in six minutes a day. Four quick questions. One focused plan. An optional side photo when you want a measured baseline. WHAT YOU GET STAND TALLER. Forward head and a rounded upper back can visibly cost you height. Improving how you stack your head, shoulders, and spine can help you stand taller. No gym required. LOOK BETTER IN EVERY PHOTO. Head up, shoulders back, spine stacked. Posture is the difference between how you look and how you could look. WORK ON HEAD POSITION. Get a focused daily routine for the head, shoulder, spine, or hip area your answers identify first. WALK IN WITH PRESENCE. Standing tall changes how people read you before you say a word. HOW IT WORKS START WITH YOUR PLAN. Answer four quick questions to receive a clearly labeled estimated starting score, a first-focus area, and a preview of your personalized six-minute session. UNLOCK YOUR ROUTINE. The subscription offer appears after your plan or optional scan preview. An active subscription unlocks your first guided session, measured results when you scan, continued sessions, and rescans. Sessions use guided videos and timers and require no equipment. ADD A SCAN WHEN YOU WANT. A side-profile photo is optional during onboarding and remains available later. Apple Vision maps visible body landmarks on your iPhone and creates a measured posture baseline. Subscription access unlocks the full measured report. If a photo cannot be analyzed, you can continue from the questionnaire estimate. Later rescans may add a front photo to refine alignment changes. TRACK THE CHANGE. A measured scan provides a 0-100 posture score, four area scores (Head, Shoulders, Spine, Hips), and your weakest area. Rescan over time to compare photos and measurements. PRIVATE BY DESIGN Your scan photos are processed entirely on your iPhone. They are never uploaded, and you can delete them anytime from Settings. Nobody sees your photos but you. WHY IT STICKS • Six minutes a day, short enough that you can stay consistent • One plan, one focus, no workout planning • An optional measured baseline you can refine over time • Streaks, reminders, and offline-friendly local storage Eligible new annual subscribers receive a three-day free trial. The annual subscription renews automatically at the price shown on Apple's purchase sheet unless canceled at least 24 hours before the trial ends. The weekly subscription has no free trial and is billed immediately. Trial eligibility, localized price, and renewal terms are confirmed by Apple before purchase.
