The app will give you a very brief summary of an NPC designed to be most compatible with fifth edition dungeons and dragons. for each NPC you will get:

-Name
-Age
-Family/clan
-Job
-Stats (st, dex, int, con, cha, wis)
-A randomly generated visual
-Current Mood
-Gender

All of which are tailored for each race. The included races are Dwarf, Elf, Human(with Goblin, Orc, Halfling and Gnome available in the full version)
All of these should give any GM a quick jump off point for an NPC when the party are being curious.
