Would like to see some improvements
During the conference the app doesn’t help you connect later with those you meet. It would be great to have the ability to star folks that you meet and provide some location aware context as to where that meet happened. Adding notes to the connect could be entered later, or even a message sent.
It would also be interesting to have a proximity alert for those you have starred (providing a user to selectively exclude themselves from discovery or blocking some).
And, based on the amount of walking and travel a person experiences at the conference, perhaps just aggregating distance travelled by day when the app is on into a collective viz of attendee travel experience?
