Tracking App

Hi,

I've seen several tracking type apps whereby users can track their friends, and other apps that track the route that you run on Google Maps.

I want to add a small feature to one of my apps so that your friends can send you a tracker invite, and then you can see your friend on Google Maps until they cancel the tracking.

What would be the architecture behind building / designing this function. Should we just update the DB every 5 seconds with your friend's current location, and then keep refreshing your map so that you can see their new position every 5 seconds, or is there a better way to achieve this.

Thanks in advance for your help.

I don't have an answer informed by professional knowledge but you could establish a socket connection between the two devices and send the co-ordinates across that way. What language/framework are you using?

Hi, thanks for your reply. It's a native Object C app run with a Parse backend.

Here's some info on Apple docs about setting up sockets between applications/devices.

Ok great, thanks... i'll look onto this.
