Add the people you want to stay in touch with — friends, classmates, colleagues, anyone on your coast. Save one thing about them. A new job, a career move, a trip, an inside joke, or something they mentioned. PeerCoast nudges you when the time is right, with something personal to say. Not a generic reminder. A real reason to reach out. Set your own rhythm. Weekly for the people you talk to all the time. Monthly for your broader circle. Every few months for the ones worth keeping on your radar. PeerCoast spaces everything out and handles the timing so you never have to think about it. When a nudge arrives, everything is already there. Who they are, what you saved, and a natural way to start the conversation. No feeds. No followers. Nothing public. Your notes stay on your device and you stay in control.
