Thanks to this program, I can easily remember someone's name, and more importantly, associate it with a face which has always been a bit of a challenge for me.
I speak with a lot of people both in person and remotely on a daily basis, and while I could remember details of their work or personal life, I always had to take a moment to re-associate a face with a name.
I still struggle with this from time to time, but I'm getting there ! ;)
