Ben Christensen, Cliff McCollum, Michael Morrow and David Gaona have never met, but they share the same hobby: Each is a part of an army of approximately 100 volunteers who help create mobile phone applications (apps) for The Church of Jesus Christ of Latter-day Saints. Tom Welch, a senior Church technical program manager, started the volunteer effort in 2006 with the launch of LDS Tech. Church members can use this website to fill out a talent profile and see which projects best fit their skill set.
