The first idea is for an app that might be named Crossed Paths. It would use the iPhone’s location capabilities to track each of its users’ movements. It would then report to each user which other users crossed paths with them each day - basically which users were in the same vicinity in any given day and perhaps even around the same time. User Profiles could be anonymous to prevent abuse but would need to be very rich in terms of describing users. If a user found that another user with an interesting profile was in the same vicinity as him/her at some point, he/she could then initiate a conversation with the other user. This creates a reverse social network of sorts helping people to make new friends etc. I expect it could be quite successful as an alternative approach to a dating application.

I would call the second idea Met2day - an application that would enable users to record details of people they met for the first time that day and create a visual timeline of their social activity for future reference. This social activity could be posted to the user’s Facebook newsfeed for example. The app could include a leaderboard of its most social users but to prevent false claims of social activity and to encourage viral spreading of the app, a ‘meeting’ would need to be confirmed by the other party (the person that the user claims to have met) - so the user would be given the option to request confirmation from each person they say they have met. For marketing purposes by the way, the app could be positioned as an anti-virtual-friendship crusade - i.e. show how genuinely social you are by showcasing your true (real-life) social encounters.
