Plexys helps people with spine conditions — especially cervical myelopathy and degenerative spine disease — keep track of how they're actually doing between appointments, and walk into their next visit prepared. Built by a spine surgeon. Your neck and back can change slowly and quietly. A slightly slower walk, a wider stance, worse balance, a stiffer neck — these are hard to notice day to day and hard to describe in a short appointment. Plexys turns the signals your iPhone already collects into a clear picture you can track over time and share with your surgeon. **MOVEMENT TRACKING BUILT FOR SPINE PATIENTS** Plexys reads your walking data from Apple Health — walking speed, step length, asymmetry, double support, and Walking Steadiness — and learns your personal baseline. Your Plexys Score shows how your mobility compares to your own usual pattern, and alerts you when something meaningfully changes. Changes in how you walk can be an early signal worth discussing with your doctor. **GUIDED SELF-TESTS (NEW)** Quick tests you can do at home, using your phone's motion sensors: • Balance & Sway — a 30-second steadiness test (eyes open, eyes closed, and heel-to-toe) • Neck Range of Motion — measure flexion, extension, side-bend, and rotation Track your results over time and bring them to your appointment. **CLINICAL QUESTIONNAIRES** Complete the validated assessments spine specialists use: • Modified Japanese Orthopaedic Association (mJOA) — myelopathy • Neck Disability Index (NDI) — cervical spine • Oswestry Disability Index (ODI) — lower back **DAILY SYMPTOM JOURNAL** Log pain, triggers, relief, mood, and sleep in under 30 seconds. See your trends, and set a gentle daily reminder so your history stays complete. **PREPARE FOR YOUR VISIT** Answer guided questions about your symptoms, history, and goals — pre-filled from your journal so you're not re-typing — and generate a clean, professional PDF to share with your surgeon. **DAILY GUIDED STRETCHING — FREE** Follow along hands-free with guided stretch routines: Wake Up, Lower Back Relief, Posture Reset, Neck & Shoulders, Wind Down, and Full Body. Each routine walks you through every stretch with a hold timer, automatic side-switching, and a next-up preview — build a daily habit and keep your streak. Plus a full library of 25 spine-specific exercises with step-by-step guidance, organized by category, condition, and recovery phase. No subscription, no paywall. **POST-OP RECOVERY TRACKER** Week-by-week guidance for common procedures (ACDF, microdiscectomy, lumbar fusion, laminectomy): what's normal, warning signs, and milestones. **FIND A DOCTOR** Search nearby spine surgeons, pain management, and physical therapy — closest first. **YOUR DATA STAYS ON YOUR DEVICE** No accounts. No cloud. Your health information is stored only on your iPhone, encrypted at rest, and never leaves it unless you choose to export or share it. --- Plexys is a tracking and preparation tool.
