Hippo's whole product is keep-in-touch nudges. We do that and a lot more. Here's how to pick.

Hippo's design philosophy is the opposite of feature-creep: do the keep-in-touch reminder loop perfectly and stop. Contact Book does the same loop alongside life events, gifts, family graph, and a journal. Pick Hippo if you want the simplest possible nudge tool; pick us if you want the texture too.
Free plan, no credit card. We host in Germany. You can export and delete everything self-serve.
