## What is Barometer ∞ Pressure Altitude?

Your iPhone already has a barometer. Use it.

Barometer ∞ gives you instant, accurate atmospheric pressure readings and your current altitude — straight from the device's built-in sensor. No signup, no subscription, no fuss.

• Live barometric pressure, updated in real time
• Current altitude in meters, powered by the same sensor pilots trust
• Four pressure units — pick Standard Atmosphere (atm), Hectopascals (hPa), Kilopascals (kPa), or Bar
• Works offline — no internet or location required to read pressure
• Native iOS design built for iOS 17 and later
• Tiny download and zero clutter

Great for:
— Hikers and climbers curious about elevation
— Weather watchers tracking pressure shifts

Barometer ∞ is intentionally simple. It does one thing — show you what your iPhone's pressure sensor sees — and it does it instantly. No cluttered dashboards, no weather forecasts you didn't ask for, no dark-pattern paywalls.
