Weather strain for today

The Problem
Migraines, headaches, joint pain, fatigue – when the weather shifts, millions feel the consequences. Regular forecasts tell you if it rains. Vorly tells you if your head will hurt.
Your doctor says: Could be the weather
Weather apps show rain, not strain
You feel it, but nobody believes you
Features
One glance is enough. Vorly works out your personal strain from 0 to 100 – from air pressure, temperature, humidity, wind, solar activity and your profile. With a pressure curve over 24 hours, seven days with Pro. On iPhone also as a home screen widget.
Once you have logged symptoms on fourteen days, Vorly shows what YOU react to. Your personal weather profile names your triggers – in black and white, and more certain with every further day.
A plan every morning, built from the forecast and your patterns, with concrete steps to tick off. Two tips are free, the full plan comes with Pro.
One tap is enough. Record symptoms with severity and a note – Vorly links them to the weather automatically. Medication too, including how well it worked, so you can see what helps you.
See today what tomorrow brings. The strain level for every day, so you can plan around it.
AQI, PM2.5, ozone and 6 pollen types – all in one dashboard.
Vorly speaks up before it starts: strain changes, official severe-weather warnings, pollen and air quality, a morning overview and an evening check-in, medication reminders – and a Sunday round-up by email. Quiet hours on your schedule.
Import from Apple Health (iOS) and Health Connect (Android). Sleep, activity and cycle data flow into your strain level automatically – no typing.
Vorly spots that your symptoms arrive, say, six hours after a pressure drop. Combined triggers, delay times, weekly and monthly reviews – and the days you felt well.
Sleep quality and menstrual cycle as triggers. Vorly shows sleep stages and how the night went, compares your week and spots hormonal patterns.
Ask Vorly anything about your weather sensitivity. Two questions a day are free, 50 with Pro. The AI knows your profile, your triggers and the current weather.
The day's UV curve and your skin type become a length of time: how long you can stay outside unprotected. Including a note on medication that makes skin sensitive to light.
Systolic, diastolic, pulse, an optional second reading and a note. With Pro, Vorly reads the numbers straight from a photo of your monitor. The history sits next to the weather, not in a separate app.
30, 90 or 180 days as a PDF: your symptoms, the weather links, your health profile and the method behind it. To take along, share or send.
How widespread respiratory complaints currently are in your region, with the trend and a comparison to last year. For Germany and the US, from official reporting data.
Science
Vorly's strain level is built on peer-reviewed studies covering more than 4,300 patients and over 330,000 analysed headache events.
4,375 users. Pressure drop 6h prior is the strongest migraine predictor.
Migraine frequency increases significantly from 5 hPa pressure drop.
6–10 hPa below standard = highest migraine risk. 73% of patients affected.
Vorly uses these findings to work out your strain level for each day.
How It Works
Tap when you feel something. Even 'No problem' helps.
After fourteen days of entries, Vorly identifies your personal triggers.
Vorly warns you before the symptoms arrive.
FAQ
About 50% of all people physically react to weather changes – with migraines, headaches, joint pain, fatigue, or circulatory problems. Medically, this is called meteoropathy. Air pressure changes are a particularly strong trigger.
The strain level is built on peer-reviewed studies (Katsuki 2023, Kimoto 2011, Okuma 2015) covering more than 4,300 patients and over 330,000 analysed headache events. It weighs eleven weather factors: pressure change, low absolute pressure, humidity and dew point, dry air, temperature change, wind, foehn, precipitation, heat, cold and solar activity. Once you have logged symptoms on fourteen days, it also follows your own pattern.
Vorly uses weather data from the German Weather Service and other meteorological providers. It measures air pressure, temperature, humidity, wind, precipitation, UV index as well as pollen and air quality – and turns them into your personal strain level.
Yes. Free for good: the strain level for today, tomorrow and the day after, logging symptoms, blood pressure, air quality, respiratory levels, seasonal trends and two questions a day to the AI.

Current prices are in the App Store and on Google Play.
