Most posture apps tell you to sit up straight. Posture 12 shows you, in degrees, whether you are actually improving. Measure your posture and mobility with just your phone — on Face ID iPhones, a live depth-sensor neck reading accurate to the degree. Then fix what the measurements find, in the minutes you actually have. RELIEF IN TWO MINUTES Neck tight in a meeting? Tap one button and get a single targeted exercise picked for where you hurt — seated or standing, office clothes, no equipment, done in about two minutes. Smart reminders through your workday open straight into a set, and every one counts toward your daily goal. A DAILY LOOP YOU CAN ACTUALLY KEEP A daily movement ring fills with everything you do — a 2-minute reset at your desk or a full session at home. Build streaks, see your week at a glance, and watch which exercises actually help you, ranked by your own feedback. MEASURE, DON'T GUESS • Live neck range-of-motion check (Face ID iPhones) — degrees, not vibes • Posture photo analysis — your alignment scored and tracked over time • Honest trends: the app only claims progress beyond measurement noise • Photos never leave your phone — only joint positions are analyzed A 12-WEEK PLAN THAT REBUILDS ITSELF Follow a structured program built from the bestselling osteopathy book — 84 days of guided routines that adapt to what you completed, how you rated it, and where your pain is now. You don't decide what to do. You open the app and follow the next ten minutes. A COACH THAT KNOWS YOUR HISTORY Ask anything — form checks, exercise swaps, what to do on a flare-up day. Your coach knows your scans, your pain log, and your plan. Every workout tracks your pain before and after, so the app learns what actually works for you. 100 ILLUSTRATED EXERCISES Every exercise drawn with anatomical detail: form cues, contraindications, and exact doses. From desk-safe chin tucks to full strength work — filtered by the equipment you actually own (none required). Tap any exercise to do a 2-minute version or generate a related workout. FREE — NOT A TRIAL These are free forever, no card required: • All 100 exercises and the full workout builder • 2-minute quick resets and the daily goal ring • Pain logging, body map, and your activity history • Your first posture scan and first neck measurement Posture 12 Pro adds the 12-week adaptive program, repeat measurements with trend tracking, and unlimited coaching — from about $5/month billed annually, with a 30-day free trial. Cancel anytime. Built for desk workers, athletes, and anyone dealing with neck pain, back pain, rounded shoulders, or poor mobility. Posture 12 is a fitness and education tool, not a substitute for medical care. If you have an acute injury or diagnosis, see a clinician first.
