Nei Gong Timer is for internal boxers and qigong practitioners. It allows you to set up any number of timers with interval durations of 1 second to 61 minutes and from 1 to 240 intervals. So you could have a "Xingyi" timer with 5 intervals of 6 minutes for a Xingyi session, a timer with 8 intervals of 3 minutes for Eight Pieces of Brocade, or a timer with 108 intervals of 15 seconds for a 27 minute taijiquan long form. Timers have a 10 to 30 second settling countdown, followed by one stroke of a singing bowl (a four-second tone). Each interval is marked by another stroke of the bowl. The end of the session is marked by two strokes. There is also a Sessions Record that records your activity.
This app is dedicated to John Lee Hooker's "Church Bell Tone Blues," just like the Da Zuo Meditation Timer.
