Know when the pressure is about to drop — the next 48 hours free, 7 days with Pro.
Barowise forecasts barometric pressure — the next 48 hours free, 7 days with Pro.
One clean screen: where pressure is now, where it's heading, and when a noticeable drop is coming. No diary to fill in, no account to create, nothing to buy but the forecast itself.
Falling pressure is one of the most commonly reported weather triggers. Some people track pressure changes alongside migraine, headache, or joint discomfort — responses vary widely, and many people feel nothing at all. The science is genuinely mixed, and Barowise doesn't pretend otherwise. It shows you the weather fact. Whether pressure affects you is something only you can find out.
The idea came from years of playing saxophone in the Paris Metro. Some mornings a whole train car seemed to share one mood, car after car — and I wondered if the weather had something to do with it. I still don't know. This app is that question, made useful.

Barowise is weather information only — not a medical device and not a substitute for professional care. It never predicts symptoms and never diagnoses anything. A calm reading doesn't mean you'll feel fine. Never delay medical care because of an app.
Weather data from Apple Weather and Open-Meteo. No ads. No account. Your data isn't sold.
Barowise Pro is an optional auto-renewable subscription (annual with 1 month free, or monthly). Payment is charged to your Apple Account and renews automatically unless cancelled at least 24 hours before the period ends. Manage or cancel anytime in Settings.
