Running problem?

You mainly use this to record running data, and the sports APP calculates and records data in different ways. "Indoor running" actually refers to a calculation-recording method. The most obvious point of this method is that it has no trajectory and lacks a dimension to determine the distance.

Of course, it is no problem to record outdoor running. What matters is accuracy. But to be honest, even if the body data is constantly revised, most running data will always have errors. If outdoor running can open the track record, the calculation result will be more accurate.
