  • Communications apps ó low bandwidth data may be available when voice is not, being able to communicate with your friends and family via multiple means can be very useful
  • First aid reference apps
  • Survival/CERT reference apps
  • Reading/games/other distractions apps ó to stave off boredom when battery life isnít an issue
  • Travel apps ó Sometimes in an urban environment rapidly finding and booking a hotel room, getting a ride share pickup, and so on, can make things a lot easier

I'd add
- ride apps (Uber, Lyft) and an account
- messaging apps (text, Skype, etc)
- Phone numbers in a separate (text) file
- govt info app or accounts (my highway departments twitter, for instance.)
- Link to the "L" schedule or other transportation info ( bus, rail, etc)

And I'm often surprised at how few people carry a charger or small battery.
