The iOS Location service seems to be pretty reliable, if a bit slow to respond to location changes. I've been using it with my home automation system for quite a while, to determine when I am within 1 kilometer, 5 kilometers, 10 kilometers, etc. On that system, I do different actions, depending on how far I am from home (changing the thermostat setpoints, mostly.)
I have a lot of faith in the iOS location services working, within an acceptable degree of range and within an acceptable timeframe. I don't need pinpoint-accurate location. I just need it to notice when I'm within a half-mile of the office or not. On Tue, Mar 31, 2015 at 1:36 PM, John F.
