About

DizzyLog

Features
Read full description

Log a headache or dizzy spell in 3 taps, right when it happens. Pick what hurts — headache, dizziness, or both — then type, severity, duration, triggers, symptoms and medication, all on one screen. Barometric pressure at that moment is attached automatically from your device's own sensor. What you log becomes one page a month: when your attacks happen, and what tended to line up with them — counted only from your own records. ā–  Built for mid-attack use • "It hurts now": a 3-tap record. Close the app halfway — what you entered is already saved • Attack timer: start it from the Home Screen widget the moment it begins; the measured duration goes straight into the record • About two hours after you take medication, Home asks "Did it help?" Answer in one tap, and which drugs work for you starts to add up • Left something half-written? After 24 hours, History gently nudges you to finish it ā–  Pressure, matched against YOUR records • A barometric forecast for your area: 2 days ahead free, 3 days and a full week with Pro • An alert before big drops (Pro) — before, not while it is already falling • Pressure shapes: sharp drop, slow drop, low and flat, calm, slow rise, sharp rise. See which of the six your own attacks cluster around; when that same shape is forecast, the chart marks it • Four Home Screen widgets: current pressure, a large 24-hour chart, the attack timer, and today's entry ā–  One page a month (Pro) • A weekday Ɨ time-of-day grid shows where your worst attacks gather • Days that lined up are counted side by side with days that did not — sleep, stress, skipped meals, water, salt, caffeine, alcohol and menstruation, everything you logged • Medications ranked by how often they worked, with how much you took and the overuse guideline on the same screen • It reports counted facts. It does not diagnose or predict ā–  Ready for the consultation room • A doctor-ready PDF (Pro) laid out like a paper headache diary: morning/afternoon/night columns, severity as + marks, medication and its effect, menstruation, symptom marks • With Pro you can read every page on screen — no printing needed • Medication is recorded by name, with days-of-use totals per drug class • Preview a free sample PDF with the exact same layout before you buy • Export everything as CSV (Pro) ā–  Free, forever Unlimited attack records, the pressure chart (2 days ahead), recent history, daily logs (sleep, skipped meals, stress, menstruation and more) and record reminders are all free. ā–  DizzyLog Pro Full history, the whole monthly page, a week of pressure ahead, pre-drop alerts, the doctor-ready PDF and CSV export. • Monthly plan (free trial included, auto-renewing, cancel anytime) • Yearly plan (auto-renewing, cheaper than paying monthly) • One-time purchase (pay once) All three unlock the same features. Your records are never taken away if you stay free. ā–  Privacy No account. Your records stay on this device only — nothing is sent to the developer or anyone else. Zero ads and zero analytics SDKs (App Privacy: Data Not Collected). DizzyLog is a journaling app, not a medical device. It does not diagnose, predict or treat any condition. Talk to a doctor about your symptoms. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://nosunosukawa.github.io/dizzylog-site/privacy.html
