Best Running Apps with Live Tracking

Haikugurl

For safety reasons, so my family can know where I am when I run, I'm thinking about using live tracking when I run. I've been using Map My Run for awhile now for all the great running stats and I've been fairly happy with it. But the upgrade is kind of pricey to get the live tracking feature. After seeing a few posts mentioning Runkeeper, I'm trying it out to see if I like it before I pay to upgrade to get the live tracking option. I also see people here are using Endomondo or Runtastic.

Any recommendations on what running app you like best? I'm looking for something that's got all the good statistic features (mapping, pace, distance, elevation, calories, etc) but also does live tracking and isn't too pricey. Thanks!
