This list is still a WIP, have more stuff I need to try out and add.
Blackberry 10 Apps: Split The Check+(PAID) - Lightweight bill splitting application that I wrote with sharing functionality and GPS location.
Allows you to easily:
-split the bill between multiple people
-share the cost per-person including your current location (optional) with others (text message, twitter, linkedin, bbm, create a personal reminder, etc).
-GPS location is shared as a google maps link so anybody can open it and see where the expense happened.
-saves your recent bill splits + location locally in the app.
