Recently I notice that in the iOS version of SkySafari 7 Plus, 7.6.6 (1171) on my phone, the lunar phase is not stated in the usual way. Instead of the conventional 0 day to 29.5 day cycle of new moon to waning crescent, it's always stated as a countdown to the new moon.
For example:
The 1-day-old Waxing Crescent would become New Moon, -28.58 days old;
The 7-day-old First Quarter would become New Moon, -22.54 days old;
The 15-day-old Full Moon would become New Moon, -15.57 days old;
The 22-day-old First Quarter would become New Moon, -7.86 days old.
I'm not sure if this is on purpose or a bug, but it's annoying.
