How to use iphone barometer

There may be many users who have bought iPhone6 or iPhone6 Plus who don't know that the new iPhone has added a sensor, which is a barometer (already equipped on some Android phones). The function of barometer is well understood, that is, the current altitude can be known by measuring atmospheric pressure. So what is the use of iPhone6 equipped with sensors?

IPhone6 has built-in health applications. Although the old iPhone upgraded with iOS8 also has this application, it can't play its full role because there is no barometer health application. Health application can not only record the number of steps, walking/running distance, but also test how many floors have been climbed, which requires barometer work. IPhone6 users enter the "Health Application", click the Health Application tab, enter fitness data, click the stair climbing in the fitness data, and then drop down and refresh to see the stair climbing data.
