Features-wise, DayZ Central is a pretty meaty offering with the base app including a full HD map of Chernarus that features:
- Full database of items, equipment, vehicles, etc
- The ability to add waypoint markers
- Building locations
- Vehicle locations
- Loot locations
Plus, for an added bonus, you get a handful of guides included in the app. What I've been doing (as nerdy as it might sound), is setting up my tablet in landscape view next to my main monitor when I'm playing DayZ. Doing this, I have an always-on loot, vehicle and building location guide at my fingertips.
This is especially handy as I pretty much spend 90% of my time in DayZ being killed by bandits, so finding loot becomes something of a necessity.
