Awesome App

I finally could get ride of my huge amount of business cards that would always got lost when I needed them. Algo, the proximity feature worked really well in an event that I attended. Would recommend.

Surprisingly addictive

I’m finding the app to be indispensable. I had to use it a few times to really get in the habit, but now I’m pulling it out every day.
