My Altitude uses GPS signals to determine your current location, showing your latitude, longitude and altitude (height from sea level) barometric pressure and water boiling point. Its a free app and does not have any limitations. In-App purchase can be used to remove the bottom advertisement and to support us. This application does not need an internet connection and works best in outdoors. By default, it uses device sensor to determine the elevation from see level, but you also have the option to use NOAA data files to get the altitude of your location. On newer devices, using device sensor is more accurate. It also allows you to get a picture of where you are and save it in photo album. Picture will be sealed with coordinates of current location along with altitude and local date/time. Barometric Pressure is calculated based on elevation. On newer devices such as iPhone 6/6+ value is being delivered directly from device built-in barometric sensor, this behavior is configurable and you can switch back to calculation mode. App Features: - Elevation from see level in meter (metric) or feet (imperial) - Change between metric and imperial systems by tapping on reported elevation - Current location coordinates including latitude and longitude - Barometric pressure in various units extracted from device sensor or calculated from altitude - Water boiling point at your current location - Current weather information including temperature, condition, humidity, wind speed and wind bearing - World Altitude, get approximate altitude (elevation from see level) of any location in the world - Save altitude data for reference - Take a picture and watermark it with elevation information and share Enjoy.
