I have mine set up to upload ride data to Strava at the end of the ride, and email a "live track" link to my wife at the start of the ride, both of which are also super easy to do through the Wahoo app. It's missing a couple of features of the bigger units (power meter being the biggest one), but that's not a significant concern for me. I found a lot of excellent in-depth information about it by searching "wahoo mini review".
