This is a very good effort that fills a gap that LIFX has not. I have been waiting since purchase to place my 2 LIFX modules under my computers control. The ios and android applications have not met my needs. The mac os x sdk appeared but 1 week before this app appeared on macupdate.
With LIFXstyle it is possible to schedule on and off times for the lights. I have schedules for turning the lights on in the morning, off at dusk, on again in the evening, shifts to purple and red and later times and then off. For the most part it works well. I am not sure that it identifies daylight savings time and sometimes the lights are not correctly synchronised. Hopefully these problems will be corrected in future betas or before final release.
I have scored this software as 4 as it is the first of its kind and easy to use.
