Narcolepsy
Read full descriptionHide full description
Living with narcolepsy means the day can turn heavy without warning. This app helps you stay ahead of it. It learns from your logged episodes when you're most likely to get drowsy during the day, and combines that pattern with live signals from Apple Watch (heart-rate variability, heart rate, sleep, daylight and activity) to estimate your current drowsiness risk — and warn you before a high-risk window. What you can do: See your live drowsiness risk — with a breakdown of why it's rising or falling Get an early warning before your predicted high-risk times Log sleep attacks, microsleeps, cataplexy and more in seconds Keep a clinical sleep diary — bedtime, sleep onset, awakenings, efficiency — auto-filled from Apple Watch sleep Track medications, including extended-release, with reminders and an intake planner Plan smart power-naps right before your dips Driving mode: tighter monitoring, earlier warnings and break reminders Export a clear report for your doctor Practical guides for everyday life with narcolepsy Private by design: Your data stays on your device. The model runs entirely on iPhone. Important: This app is a self-tracking and organization tool. It is not a medical device and does not provide a medical diagnosis. Risk estimates are guidance based on self-observation and wearable data — not a substitute for professional medical advice. Never rely on the app alone for decisions about driving or treatment; always consult your doctor.

Verdict
The clearest difference is in-app purchases: Narcolepsy at none against NerveLog's 2. Narcolepsy also leads on device support (3 vs 1). NerveLog's advantage is update cadence (every 2 days vs weekly) and iOS requirement (17.0 vs 26.4). On price and ads there is nothing between them.
