Your body feels the weather. Now you'll see it coming.
Your body's forecast. A daily heads-up for migraines, joint pain, allergies and family heat safety — with exactly what to do about it.
Other weather apps tell you the temperature.
They never tell you it's a migraine day.
A pressure drop triggers a migraine. Cold damp air flares arthritis. A pollen spike wrecks an asthmatic's morning. A heat wave endangers kids and elderly. The forecast already holds the warning — most apps just never translate it.
Three steps. One clear message a day.
No dashboards to read, no numbers to decode. You set it up once, and Bo — your BodyCast companion — does the watching.

BodyCast, in plain terms
What is BodyCast?
BodyCast is a free iOS app that turns the daily weather forecast into a personal health heads-up. Instead of just showing the temperature, it reads pressure, humidity, UV, pollen and air quality, then tells you how the day will affect your migraines, joints, allergies or family — and exactly what to do about it.
How does BodyCast know it's going to be a migraine day?
BodyCast watches barometric pressure using free ECMWF / Open-Meteo forecasts. When it detects a sharp pressure drop — a well-known migraine trigger — it warns you the evening before and the morning of, with a clear action like pre-medicating early. You set your sensitivity so the alerts match your body.
What conditions can BodyCast track?
BodyCast covers migraines (barometric pressure), joint pain and arthritis (cold, damp and pressure), allergies and asthma (pollen, PM2.5 and ozone), and family heat and UV safety for kids and the elderly. You can track several at once and get one combined daily message.
Is BodyCast medical advice?
No. BodyCast is a forecast of weather-related trigger conditions, not medical advice or a diagnosis. It helps you anticipate and prepare for days that may affect you. Always follow your doctor's guidance for treating any health condition.
Is my data private?
Yes. BodyCast needs no account and no sign-up. Your conditions, location and preferences stay on your device, and notifications are scheduled locally on your phone. Your location is only used to fetch your local forecast — it is never sold or shared.
How much does BodyCast cost?
BodyCast is free. It uses free, open weather and air-quality data (ECMWF via Open-Meteo), so there's no subscription to get your daily heads-up. It is coming soon on iOS, with Android to follow.
