I’ve been toying with CRM and contact management tools lately.
I believe Cloze does what you’re looking for, although it does use a hosted online SaaS model.
I’m not affiliated in any way, I just used it recently during a trial and found it helpful.
You’re talking about Cloze.
This is literally what it’s made for. You can go this simple, or you can go way further.
It has a free version that’s probably right up your alley.
I’m a business owner and I use the Pro version and it paid for itself literally 1000x over in the first 24 hours.
The first day it auto-recommended I reach out to an old contact at a new company because we stay in contact “every 4 months.” Sent an email I would’ve never sent, and boom... lots of money.
Obviously you’re using it for networking purposes, but it all applies.
Integrates with just about everything (including your phone calls).
