Cafactor vs Migraine Tracker & Diary

Caffeine Hourglass is now Cafactor — rebuilt from the ground up. What began as a simple caffeine timer has evolved into a full physiological model that adapts to your biology in real time. Version 2.0 isn't an update. It's a new category of health tool. Know your caffeine. Protect your sleep. Log a drink in seconds. Cafactor computes your real-time caffeine curve using a peer-reviewed pharmacokinetic model — complete with a realistic absorption phase, first-order decay, and your personal biological parameters. See whether you can safely have one more coffee, and exactly when your levels will drop below your personal sleep threshold. Personalised to your body Set your sex, height, weight, and age. Cafactor applies the Boer (1984) lean-body-mass formula to calculate how caffeine distributes in your specific body. Add smoking status, hormonal medication, or pregnancy for a half-life that's truly yours. Your tolerance to caffeine — derived automatically from 7-day history — rounds out the picture. HealthKit: exponentially smarter Connect Apple Health and Cafactor transforms from a tracker into an adaptive metabolic coach: • Exercise modifier — Recent vigorous workouts temporarily speed up your metabolism. Cafactor detects this from HealthKit and adjusts your decay curve automatically. • Sleep-adaptive threshold — Last night's poor sleep tightens your safe window today. Great sleep? More room for your morning ritual. • HRV & Recovery (Apple Watch) — Daily heart-rate variability fuses with sleep quality to create a PhysiologicalState score, shifting your optimal intake windows and adjusting thresholds by up to 40%. • Progressive calibration — Recency-weighted regression over 30 days of sleep and HRV feedback automatically refines your personal half-life, growing from Preliminary to Reliable confidence as data accumulates.

A calm, private diary for migraine and headache. Log an attack in two taps, then put the phone down. Balm is built for the moment you're in pain: dark, quiet, and fast. Nothing to set up before your next migraine, and nothing asked of you that can wait until you feel better. WHEN IT STARTS • Log a headache or migraine in two taps. Pain and symptoms are optional — add them later. • A calm, dark screen with no glare, made for light-sensitive eyes. • Start from your Lock Screen, a widget, or your Apple Watch. WHEN YOU FEEL BETTER • Add pain level and location, symptoms, triggers, and the medication you took. • Keep your own list of medications and watch your medication days against reference thresholds. FOR YOUR DOCTOR • One clear page for your appointment: headache and migraine days, your MIDAS disability score, medication days against ICHD-3 reference thresholds, and the patterns Balm found. • Export everything as CSV or a backup file whenever you want. SEE YOUR PATTERNS • A calendar of migraine, headache, medication, and clear days. • An air-pressure forecast from Apple Weather, so you can see the pressure behind your attacks. • Balm can show your sleep, heart-rate variability, and cycle from Apple Health beside your entries. PRIVATE BY DESIGN • No account. No ads. Never sold. • Your diary stays on your phone. Turn on iCloud to sync privately across your own devices. • Balm is a diary, not a medical device. It does not predict, diagnose, or treat. Subscriptions automatically renew unless canceled at least 24 hours before the end of the current period.
