Our app comes with a brand new application for Apple Watch. There is current ground and MSL pressure available, you can also quickly check your current altitude and weather conditions. Two separate barometer screens - the first one shows pressure at mean sea level, which is what weather stations report; the second one is pressure at ground level at your current position. Devices with built-in sensors will get values from it and for those without sensors, the pressure value is reported by the nearest weather station. You can save any current value to compare pressure from other days. What's coolest is that you can swipe through multiple units and instantly see the pressure in the value you are interested in, including: - pounds per square inch - millibar - hectopascal - kilopascal - millimeter of mercury - bar - inch of mercury With one screen swipe, you can see an altimeter gauge with current values, our precise altitude calculation algorithms (which involve GPS, network services and calibrated pressure sensors) we deliver you the most accurate elevation info as possible, in barometric units or if you prefer, you can swipe over to metric and imperial units. Custom notifications. You can now add time-based notifications: just setup the time and days on which you want to receive notifications with current pressure values and voila. You can also set a pressure level alarm, above or below which the device will warn you. https://mysticmobileapps.com/legal/terms/barometer https://mysticmobileapps.com/legal/privacy/barometer
