Im a seminary student, and over the past two years I have found Logos to be incredibly valuable. I have bought thousands of dollars worth of materials, enough to fill a wall of an office, and all those books travel with me wherever I go thanks to Logos mobile. I can do word studies or search verses and quotes wherever I go. I hope that Logos will continue to add features from the desktop version to the mobile one, but even as it stands this is a must-have app for theologians.
