Falling Glass: Barometer
Air Pressure Alerts & Trends
Free · In‑App Purchases
Old sailors said “the glass is falling” before a storm. Falling Glass watches the pressure for you and tells you when it starts to drop.
Old sailors said “the glass is falling” when the barometer dropped ahead of a storm. Falling Glass is that barometer for your iPhone and Apple Watch: it reads the pressure sensor built into your device, shows which way the pressure is heading, and alerts you when it starts to change.
MADE FOR
• Headaches and migraines: many people notice headaches when the weather changes. Get an alert when the pressure drops, and keep a log to see how your headaches line up with it.
• Fishing: many anglers watch for falling pressure ahead of a front. Know when it’s falling, and log your catches against the barometer.
• Weather watching: a classic barometer dial and the trend over 3, 12 and 24 hours.
FEATURES
• A barometer dial from Stormy to Very Dry, with a brass hand showing where the pressure was 24 hours ago
• The trend in plain words: steady, rising or falling, slowly or quickly
• An alert when the pressure changes by the amount you choose
• A chart of the last 2 days, or a week or a month with the Upgrade
• Home Screen and Lock Screen widgets
• Apple Watch app and complications, free. With a complication on your watch face, your watch can take readings more often.
• hPa, mb, inHg, mmHg or kPa
• Set your altitude to see sea-level pressure, like a weather report
NO ACCOUNT
Readings come only from your own barometers. No account, no sign-up. Your location is used to set your altitude, name the place and, if you turn it on, take a reading when you move.
FREE, WITH ONE UPGRADE
The barometer, trends, the 2-day chart, widgets, the default alert and the Apple Watch app are free, with ads. A single Upgrade removes ads and adds a week or month of history, your own alerts and the log.
Falling Glass shows measured pressure. It doesn’t forecast the weather. Not medical advice.
