Monica looks great. I had the same pain point and built Bardun (https://www.bardunapp.com/ https://www.bardunapp.com/) as a iOS app instead of a website. Bardun brings together freeform notes and contacts to capture relationship information. For privacy, the app stores information locally on-device only. Sync of contacts via phone, Google mail or calendar is possible. Contact information is streamed to the device rather than stored on a server.
