About

Cranio

Read full description

Cranio is a headache diary built by a cluster headache sufferer who couldn't find a tracker fast enough to use mid-attack — and smart enough to be worth it afterwards. Log attacks in seconds A fast, guided flow captures type, intensity, location, symptoms and treatment — with your usual details pre-filled. Start a live attack from the home-screen widget or lock screen and a Live Activity times it from your Dynamic Island. Local weather (temperature, pressure, humidity) is captured automatically at onset. See where you stand at a glance Your Overview shows today, this week and this month, medication check-ins ("Did you take your 8:00 Verapamil?"), your MIDAS disability grade — calculated with the real clinical instrument — and streaks and achievements that make consistent tracking feel worthwhile. Medication tracking that actually helps Add your medications once and Cranio pre-selects them when you log, reminds you at your usual dose times by name, tracks adherence day by day, and flags rapid re-dosing and medication-overuse risk. Understand your headaches with Premium • Trigger correlations — real statistics from your own diary: air pressure, sleep (via Apple Health), triggers and weekday patterns • Bout intelligence — built for the cluster cycle: which day you're on, whether it's easing, and how it compares to your past bouts • Pressure warnings — a heads-up when a sharp barometric drop is forecast near you • Advanced reports — severity, duration, time-of-day and sleep trends, plus your MIDAS score month by month • Doctor PDF report — your whole diary as a clean, printable summary for appointments • Medication insights — how often each treatment actually helped, and how fast Your data stays yours Everything lives on your device, with optional private iCloud sync and Face ID lock. Export and backup are always free — no account, no ads, ever. Logging is free forever. Premium is a simple monthly or yearly subscription, cancel anytime. Cranio is a tracking tool, not a medical device — always discuss your headaches and treatment with your doctor. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
