mikee123 - After having been in the same boat (I believe we had exchanges on this topic) I perked at the opportunity to use a GeoFence based system with iViri. So far there have been a few kinks to work out in the beta versions I've been testing, but overall the performance has been great. Much better battery life (save for the usual iOS BS) and the accuracy has been pretty spot on for me. I set it to 250m and when I'm about halfway down my road, I receive my notification that the Alarm has disarmed successfully. Also makes it easier not having to think about "pausing" the locator plugin and such as well. Now with MultiSwitch capabilities, I've got 1 MS for both of us, and a PLEG that takes care of the automation based on that. Works great for me now.
