Turn your iPhone into a fast and accurate thermometer. Check the current outdoor temperature, humidity, pressure, and wind at your location. Used by over 5,000,000 people worldwide! Most weather apps merely display data from the nearest weather station, which could be hundreds of kilometers away and more that an hour outdated. We utilize AI technologies to combine data from multiple weather stations, providing accurate predictions for temperature, humidity, pressure, and wind at your current location in real-time. Features: - Shows temperature, humidity, pressure, and wind. You can use it as a thermometer, barometer, or hygrometer. - Use your current location or choose any location on a map. - Minimalistic design: shows only the necessary data. - Displays Celsius and Fahrenheit degrees on a beautiful thermometer picture. - Switch between Celsius and Fahrenheit degrees with a tap. - Helps you quickly decide what to wear. - Helps you keep track of the weather during heat and cold waves. Permissions: - Location (optional): Used to automatically show the weather for your current location. You can also choose a custom location manually from the map — no permission is required for that.

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
