Barometer ∞ Pressure Altitude

Instant pressure and altitude from your iPhone's built-in sensor. Pick your unit — atm, hPa, kPa, or bar. Free, no subscription, no signup required.

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 — Students, teachers, and anyone learning about atmospheric science — Anyone who wants a clean, fast reading without wading through ads-riddled "pro" alternatives

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.
