Atmospheric Pressure

Atmospheric Pressure turns the barometer in your iPhone or iPad into a clear pressure monitor, logger and local trend viewer. See the current atmospheric pressure at a glance, record readings at your chosen interval and understand how conditions are changing over time. Raw and calibrated values stay together, while movement, gaps and unusual jumps are identified so that unreliable samples are treated with appropriate caution. Features: • Live atmospheric pressure in hPa or kPa • Manual and altitude-assisted calibration • Clear local pressure tendency and change over time • Smooth charts for one hour, six hours, 24 hours, seven days or all readings • Individual reading history with swipe-to-delete • CSV and PDF exports • Optional pressure notifications • Home Screen widgets and Live Activities • iPhone and adaptive iPad layouts • Optional always-on display behaviour while charging Your pressure history is stored on your device. Exported files leave the app only when you choose to save or share them. Background logging is best-effort because iOS and iPadOS decide when apps may refresh while closed. Atmospheric Pressure is intended for personal reference and general interest. It is not an official weather forecast, aviation or marine instrument, emergency warning tool, or safety-critical system.
