## What is Rin Sky?

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.

■ 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
• Log your usual warning signs before the pain (yawning, a stiff neck, flickering lights…) — even when nothing hurts yet

■ Pressure, matched against YOUR records
• A barometric forecast for your area, as a chart and a sky you can scrub through time: the next 24 hours free, 3 days and a full week with Pro
• An alert before big drops — before, not while it is already falling (free for your first 14 days, then Pro)
• 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

■ One page a month (Pro)
• A weekday × 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
• Headache days per month, before and after starting a preventive, side by side
• 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

■ 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
• Visit prep (Pro): add your next appointment and questions for your doctor. Reminders come 3 days and 1 day before, and your questions go on page 1 of the PDF
• 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)

■ Free, forever
Unlimited attack and warning-sign records, the next 24 hours of pressure and sky, your last 3 days of history, daily logs (sleep, skipped meals, stress, menstruation and more) and record reminders are all free. For your first 14 days, full history and pre-drop alerts are free to try too.

■ Rin Sky Pro
Full history, the whole monthly page, before-and-after for preventives, a week of pressure ahead, pre-drop alerts, the doctor-ready PDF, visit prep 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.

■ 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).

Rin Sky is a journaling app, not a medical device. It does not diagnose, predict or treat any condition. Talk to a doctor about your symptoms.

## Version history (last 5 releases)

### 1.5.1 — 2026-10-02

We're now Rin Sky (formerly DizzyLog). Your records, purchases and widgets are unchanged.
• Fixed: on iOS 26 the share sheet for the doctor report or CSV opened as a narrow, clipped window.
• Fixed: visit reminders and pressure-drop alerts could arrive twice.
• Before and after preventive medicine now says when there aren't enough earlier records to compare.
• Fixed: after a Pro plan ended, pre-drop alerts showed as on but never sounded.
• Smaller display fixes.
Open the app to see “What's new” for why we changed the name.

### 1.5.0 — 2026-10-01

A big refresh, inside and out.
• A warm new look that matches the icon, with softer light so it won't glare mid-headache.
• A sky on Home with a time slider: slide it to see the forecast pressure and sky ahead.
• Severity is now shown as rings — countable even if colors are hard to tell apart.
• Log your warning signs (yawning, stiff neck, flickering lights…) even before any pain.
• Visit prep: add your next appointment and questions for your doctor. You'll get reminders 3 days and 1 day before, and your questions appear on page 1 of the doctor report (Pro).
• Compare headache days per month before and after starting a preventive (Pro).
• The guide has been rewritten in 7 short chapters.
• We've revised what's free. The next 24 hours of forecast and your last 3 days of history are free, and pressure-drop alerts and full history can be tried free for your first 14 days. Logging stays completely free.
• Fixed: the same pressure-drop alert could sound again each time you opened the app.
Open the app to see “What's new” for the details and the reasons behind each change.

### 1.4.2 — 2026-09-28

• Fixed an issue where the app could close right after launch on iOS 27.
• Fixed: Today's habits and Log now could not be closed with Cancel or Save when opened from a widget.
• The plans screen no longer shows the free trial to an Apple ID that has already used it.
• The doctor-visit PDF is now always reachable from the Insights tab.

### 1.4.1 — 2026-09-14

Small fixes:
• When pressure barely moves, the change now reads 0.00 instead of -0.00.
• Thresholds in the pressure shape definitions and the monthly summary (for example "4 hPa in 6 hours") now use your region's unit, inHg in the US.

### 1.4.0 — 2026-09-11

1.4.0 — Your records now become one page a month.

• Insights rebuilt as a single page: when your attacks happen and what lined up with them, shown as figures with denominators (Pro)
• A weekday × time-of-day grid, medications ranked by how often they worked, and how much you took against the overuse guideline — all on the same page
• Pressure shapes: six named forms. See which your attacks cluster around; when that shape is forecast, the chart marks it. Tap a shape for its definition
• The barometric forecast now reaches a full week ahead (Pro). Free stays at 2 days
• About two hours after you take medication, Home asks "Did it help?" — one tap and it's recorded
• With Pro, the doctor-ready PDF can be read on screen, every page, with no printing
• The app icon now matches the colours used inside the app
• A monthly plan joins the lineup. The free trial is on the monthly plan (yearly and one-time purchase are unchanged)
