Glympse (www.glympse.com) is probably one of the most useful services when making a car trip. The free service allows you to share your journey with friends or family so that they can track you in real time. For instance, imagine you're meeting up with a friend in the city. You can give them a Glympse along with your ETA, allowing your compadre to see where you are (and perhaps preventing an unnecessary call when you're running late).
Gympse originally arrived on Windows Phone back in 2011 and before that it was even on Windows Mobile 6. The app had a handful of updates jumping from 1.0 to 2.0 in five months, but after November 2011, the well went dry. The deserting was particularly painful because it wasn't until Windows Phone 8 and the background GPS tasks that Glympse had the potential to be fully unleashed. On Windows Phone 7, the Glympse app had to stay in the forefront, losing the signal if tombstoned.
However, June 17, 2014 is the day Glympse finally returned to Windows Phone.
