How to count the steps for iphone?

With the latest iOS8 system, you can check the number of steps you take in a day on the iPhone without other third-party software. In iOS8 system, there is a "health" function, where you can see the data you want to view.

In the Health Application, in Health Data, find the Fitness Data column, and then click Enter.

Then you can see the number of steps, frequency+distance, etc. After clicking enter, you can view the detailed data.

Taking steps as an example, we can see the current walking frequency. In addition, it is suggested to check the option of "Show in Chart Summary", which can be viewed directly in the chart summary column in the future.

As shown below, you can see the frequency, distance and how many floors you climbed. For the current iPhone6 model, you can see the floor you climbed all day. If it's an iPhone5s, because there is no air pressure sensor, you can only see the number of steps and the distance.
