Runners gather their running data to exercise more efficiently during exercise, and check their exercise data from time to time using historical data as an indicator to achieve better records. It basically sends user's exercise data to the app and provides functions. Unlike conventional GPS clocks that visually show exercise information during exercise, there is a difference in that DALRING informs by voice. More than 100 million people from all over the world run while looking down and looking at the clock. This product allows users to check their exercise records while running purely without taking this posture. In addition, DALRING is a voice support service and is expected to have a social effect in that it is also available for disabled people.
