Barometer plus Altimeter vs Barometer for Watch

Barometer displays the current barometric pressure. For this purpose, the air pressure sensor of your phone or tablet is being used. The Barometer is the current air pressure, the measured maximum and minimum. Furthermore, to increase the accuracy of the measured value of the sensor can be moved. Note not all devices have the air pressure sensor. We tested the app with many current devices, such as iPhone 6, iPhone 6 plus, iPad Air 2, etc. Keyword: Barometer, air pressure, air pressure, weather indicators, altimeter

Pressure and altitude. Beautifully clear. Barometer turns the built-in sensors on your iPhone, iPad and Apple Watch into a clear view of the conditions around you. Check a reading at a glance, follow pressure changes, or explore your altitude as you climb. PRESSURE, IN PERSPECTIVE • Atmospheric and estimated sea-level pressure • Pressure history, trends and changes over time • A pressure-based weather outlook • Optional pressure-change notifications A CLEARER VIEW OF ALTITUDE • Altitude readings and elevation charts • Calibration using a known altitude or available sensor references • Ascent, descent and elevation range • Latitude and longitude • Estimated boiling point of water at the current pressure MADE FOR YOUR DEVICES • A dedicated Apple Watch app • Watch complications and iPhone widgets • Siri and Shortcuts support • Control Center shortcuts • Your choice of measurement units • CSV export for saved measurements Core pressure and altitude measurements work offline using your device’s sensors. Location access enables additional information, including estimated sea-level pressure. Requires iOS 26, iPadOS 26 or watchOS 26. Available readings depend on your device’s sensors and permissions. Pressure-based weather information is an estimate, not an official forecast.
