CrossHelmet 对比 Pressure Altimeter 的使用情况和统计数据

Pressure Altimeter converts your device's barometric pressure sensor reading to an altitude above sea level.   Requires iPad Air 2, iPhone 6, or Apple Watch Series 3 or newer for pressure sensor capability. Now you can monitor your elevation or cabin altitude accurately and in real time. Works in airplane mode. No GPS required. We have also included a vertical speed display so you can see the rate that you are climbing or descending. Features: - Altimeter setting (inHg or hPa/millibars.) - Altitude display in either feet or meters. - Vertical speed in feet per minute or meters per second. - Vertical speed direction (up/down) and warning if excessive rate detected. - Saves Maximum and Minimum altitudes reached. - Includes Apple Watch support. Note: A current altimeter setting for your location is required in order to convert the pressure reading into an accurate altitude.
