In Lingyun Fitness, the ten-second and four-minute alternating exercise mode is tabata exercise mode, so its alarm clock is tabata alarm clock, which can be realized by many softwares. I use actrainer's exercise timer, which can be downloaded from app store like pea pods. By default, it has a 4-minute tabata.

Of course, you can also use FitTime, one of Lingyun Fitness's own timing software.
