I'm working on an iPhone app that show where everyone else is around you - in real-time.

Its on the iTunes store, but its still in beta: https://itunes.apple.com/us/app/h34t/id949092708?ls=1&mt=8

This is really cool. I've thought of doing something similar. What are you using for the back-end?

Thanks joshmn

The backend is written in NodeJS with the SailsJS framework (which I used for Socket.IO support).

It runs in a Docker container on an AWS Autoscaling group with an RDS database.

Its been a blast to build
