Multiple Sclerosis Tracker catches what your memory cannot. Log relapses as they happen, track how your DMT is working, record EDSS changes over time, and walk into your neurologist appointment with real data instead of guesses. Built for people living with relapsing-remitting MS, secondary progressive MS, primary progressive MS, and clinically isolated syndrome. Whether you are newly diagnosed or decades in, this tracker adapts to your disease course. SYMPTOM TRACKING MS symptoms shift hour to hour. Capture them as they happen: - Fatigue severity with time-of-day patterns - Spasticity and muscle stiffness levels - Numbness, tingling, and pins-and-needles by body region - Vision changes and optic neuritis episodes - Cognitive fog, word-finding difficulty, and processing speed - Balance, dizziness, and gait problems - Bladder and bowel dysfunction - Lhermitte sign occurrences - Uhthoff phenomenon and heat sensitivity - Pain types: neuropathic, musculoskeletal, tightness RELAPSE LOGGING Prove it happened, prove it mattered: - Relapse start date, peak, and resolution timeline - Steroid treatment (Solu-Medrol) tracking with taper schedule - New or worsening symptoms during relapse - Recovery percentage and residual deficits - Relapse frequency and annualized rate DMT MANAGEMENT Track every disease-modifying therapy: - Infusions: Ocrevus, Tysabri, Lemtrada with appointment scheduling - Injectables: Copaxone, Kesimpta, Avonex, Plegridy, Betaseron - Orals: Tecfidera, Gilenya, Mayzent, Aubagio, Vumerity - Lab monitoring: JCV antibody index, lymphocyte count, liver function - Side effect tracking per medication - Insurance prior auth and refill management MRI AND TEST TRACKING Every scan, every score, every lab result in one timeline: - MRI dates with lesion counts (new, enhancing, stable) - Brain and spinal cord lesion tracking - EDSS score history with progression alerts - Visual evoked potentials and OCT results - Vitamin D levels and other labs INSIGHTS AND REPORTS See your MS over months and years: - Relapse frequency trends - Symptom correlations with weather, stress, sleep - DMT effectiveness comparison across switches - EDSS progression timeline - PDF and CSV exports for neurology visits LIFESTYLE FACTORS The stuff your neurologist asks about that you can never remember: - Sleep quality and fatigue correlation - Exercise tolerance and deconditioning tracking - Heat and humidity impact on symptoms - Stress levels and flare triggers - Diet and supplement logging MS-FRIENDLY DESIGN Built for the days when your hands do not cooperate and your brain is fog: - Quick logging for brain fog days - Voice-to-text when typing is hard - Large text options for vision issues - Offline mode for infusion centers - Apple Health sync Generic trackers do not understand that Tuesday's numbness matters more than Thursday's headache, or that three relapses in twelve months changes your treatment plan. MS Tracker does. Disclaimer: Multiple Sclerosis Tracker is for informational and personal tracking use only. It is not a medical device and does not provide medical advice, diagnosis, or treatment. Always consult a qualified healthcare professional for medical concerns. EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
