A running software, using the built-in GPS function of iPhone, records some data such as distance and speed. RunKeeper can be used for running, cycling, walking, hiking, skiing and other outdoor fitness activities! It doesn't matter without a Nike iPod sports suit. As long as you install iPhone and RunKeeper software, users can easily grasp the speed, time and distance of exercise.
Using the GPS function of iPhone, RunKeeper can track and measure the user's movement, which will not affect the user's listening to music with iPhone during the movement measurement. Most conveniently, when users save records, RunKeeper can also upload the records to the personal web page provided for users, so that users can view all the historical records, learn some evaluation data, and also view their own sports roadmap. ?
You can enjoy the same or even better service without paying extra for a Nike iPod sports suit. Why not?
