Same, I’ve been using https://clay.earth for this with good results. Biggest things I’ve noticed:

• Taking quick notes after interactions with “I can get” and “I can provide” helps when trying to remember things before your next conversation
• Clay will automatically update location and remind you about people without you needing to set reminders manually, which removes a lot of grunt work
• People see through periodic “it’s been a while!” texts sent on the first of each month. Thoughtful gifts and things like holiday cards with a handwritten note go a long way toward making things feel intentional.
