Friend Roulette by Adam Alpert

Friend Roulette is a small, intentional app for one job: nudging you to reach out to the people you care about, on the cadence you set.

Pick the friends, family, and contacts you want to stay in touch with. Choose how often you want to connect - weekly, monthly, quarterly, or yearly. Each day, the app rolls the dice and surfaces one person from your circle. Tap to text or call. After the conversation, log a quick note so the next roll respects what you've done.

That's the whole app. No feed. No social network. No optimization for engagement. Just you, your people, and a quiet daily nudge.
