Cheng Xian Xiu Lian is the Daoshi phrase for practice: "Become Immortal, Elevate Practice." What happened here is instead of having three apps, a meditation timer, a fine-grained neigong timer, and an open-ended timer, cluttering up my phone, I just combined the three in one app.There's a help file on the app that explains how to use all three. Personally, I use the open-ended timer for daily practice and the neigong periodically to deepen things like my taijiquan longform.
