Locket, the private social app for close friends, is riding a new wave of momentum with Rollcall, a weekly prompt that’s resonating especially strongly with Gen Alpha. The feature builds on what made Locket a hit in the first place: simple, personal photo-sharing that shows up right where you live on your phone—the home screen and Lock Screen.
Locket first surged up the App Store in early 2022 by turning Apple’s widgets into a social surface. Friends’ new photos would quietly refresh in your widget, pulling you back into the app and inspiring you to post something of your own. Rollcall follows the same philosophy, but with a fresh twist: it uses Live Activities to bring your friends’ weekly moments onto the iPhone Lock Screen and the Dynamic Island, making the experience feel immediate and communal.
Every Sunday, Rollcall nudges you to share favorite moments from the past week. Instead of a standard push notification, it appears as a Live Activity, creating a lightweight, can’t-miss hub for your group’s updates. According to CEO Matt Moss, that Lock Screen presence is a powerful driver of participation. As friends start posting, it feels like everyone’s doing it together—more like a shared ritual than a feed you scroll.
The results have been striking. Locket now has more than 91 million lifetime installs across iOS and Android, based on Appfigures estimates. In Rollcall’s first week, users generated over a million shares. Well over a quarter of active users now post a Rollcall each week, and roughly 80% of the feature’s earliest active participants are Gen Alpha.
Locket is also seeing a shift in how different generations use the app. For many younger users, it’s becoming a primary way to stay connected with a tight circle—sending photos directly to a group of 10 to 20 close friends rather than broadcasting to a wider audience. That intimate, friends-first dynamic is central to Locket’s appeal.
With Rollcall gaining traction, the team is exploring what comes next. Video is the obvious addition, but the roadmap goes beyond visuals. Think music that defined your week, places you visited, or gentle prompts that help you remember meaningful moments you might otherwise forget. While Locket isn’t planning to support AI-generated photos or videos, it is considering AI that adds value behind the scenes, like creating collages or assembling memory highlights from your real photos.
Another focus is turning digital exchanges into real-world connection. That might be as simple as a timely reminder to call or text a friend—features designed to strengthen actual relationships instead of chasing short-term novelty. As Moss puts it, there’s enduring demand for genuine communication with people you truly know.
Locket monetizes through a subscription and, with a 15-person team, has been profitable since last year. If Rollcall is any sign, building around Apple’s native surfaces—widgets, the Lock Screen, the Dynamic Island—can make sharing feel natural and effortless. And when social updates greet you right on your phone’s front porch, participation becomes a habit, not a chore.
