Almost perfect!!!

The app works great although the update period without sending a ping notice takes too long. I have used it frequently with no problems at all. The ping notice is extremely fast and reliable. The support has been great so far, I asked for a link and immediately received it the very next day. I have not experienced any significant battery drain on my iPhone so far. Overall rating is very good except for automatic updating without ping notice.
