AFib Tracker is a heart rhythm diary for the moments that count - the flutter at 3 a.m., the skipped beat in the parking lot, the episode that shows up out of nowhere. Log every atrial fibrillation event, capture your pulse, and bring real data to your cardiologist. Built for adults newly diagnosed with AFib, people on anticoagulants, post-cardioversion patients, and anyone living with paroxysmal, persistent, or permanent atrial fibrillation. EPISODE LOGGING Capture an AFib episode the way it actually unfolds: - Onset time and end time with one-tap timers - Heart rate during, before, and after - Symptoms: palpitations, chest tightness, shortness of breath - Dizziness, lightheadedness, near syncope - Fatigue and exercise intolerance - Anxiety and panic that came with it - What you were doing when it started - Whether it converted on its own or required intervention HEART RATE AND RHYTHM Track your cardiac numbers across the day: - Resting heart rate trends - Pulse regularity check-ins - ECG readings from connected devices - Blood pressure logs - Time in AFib versus normal sinus rhythm - Wearable heart rate sync via Apple Health MEDICATION MANAGEMENT Track the full anticoagulation and rate control regimen: - Anticoagulants like warfarin, apixaban (Eliquis), rivaroxaban (Xarelto), dabigatran (Pradaxa) - Beta blockers and calcium channel blockers - Antiarrhythmics like flecainide, amiodarone, sotalol - INR readings if you are on warfarin - Missed dose alerts and refill reminders - Side effect monitoring - Cardioversion and ablation history TRIGGERS AND LIFESTYLE Find what tips you into AFib: - Caffeine, alcohol, and dehydration - Stress and poor sleep - Heavy meals and large portions - Cold or flu illness - Vagal triggers and posture changes - Weather and barometric pressure - Exercise intensity - Custom triggers you discover INSIGHTS AND REPORTS Months of entries become a picture your cardiologist can read: - AFib burden over weeks and months - Episode frequency and duration trends - Heart rate distribution charts - Trigger correlations with statistical weight - Medication response and INR stability - PDF and CSV exports for cardiology and electrophysiology visits DESIGNED FOR HEART PATIENTS - Quick logging during an active episode - Calm, low-anxiety interface - Large buttons and clear charts - Apple Health sync for steps, sleep, and heart rate - Offline mode for when you have no signal - Optional biometric lock for privacy HEALTH PATHWAYS - Vagal maneuvers and breath pacing guides - Stress reduction techniques for AFib management - Education on stroke risk and CHA2DS2-VASc scoring - Lifestyle changes that support sinus rhythm - Guided relaxation exercises for episode anxiety PRIVACY AND SECURITY Your health data belongs to you. AFib Tracker stores your information securely on your device and in your private cloud account. We never sell or share your personal health information with third parties. Atrial fibrillation does not run on a schedule, and neither does AFib Tracker. Catch the patterns hiding between episodes, prove to your electrophysiologist what you have been feeling, and walk into every appointment with the data already done. Whether you were just diagnosed last week or have managed AFib for years, this app gives you a structured way to track what matters - episodes, heart rate, medications, triggers, and lifestyle factors - so you can have better conversations with your care team and make informed decisions about your treatment plan. Disclaimer: AFib 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/stdfree/
