I use a list in the Reminders app on iOS just for keeping track of people's names. Each reminder is titled after the name of a business, and its notes contain a list of people I've met along with brief descriptions of them and important events going on in their life. Each reminder is geofenced to the business it's attached to. Thus, when I get within the vicinity of any of the businesses in that list, it shows me the reminder. Kind of like a Rolodex. It doubles as a flash card of sorts when I don't patron the business that day. I don't depend on it as much these days as this simply existing helped me get better at name recall, but it was immensely helpful when I created it.
