High above the Great Plains, a virtual woodpecker is currently trekking toward Alaska to deliver a message to an anonymous pen pal. Simultaneously, a zebra finch named Tucker is winging its way to Manhattan, carrying a user’s digital sketch of the Cool S. These messages don’t arrive in milliseconds; they take hours or even days to reach their destination, depending on the bird’s flight path. This intentional delay is the core premise of Roost, a viral “slow-cial” app that is gamifying the return of the carrier pigeon in an era defined by digital exhaustion.
Escaping the Instant Notification Trap
Roost has gained traction by offering a deliberate break from the hyper-connected nature of modern smartphones. While mainstream platforms demand constant attention, Roost introduces friction by design. “Everything on a phone is instantaneous these days — every single thing you do, it’s like you’re always getting some notification,” Roost creator Logan Mendelsohn explained to TechCrunch. “It’s resonating with people in a way where they don’t feel pressure all the time to have to do something.”
How the Rookery Works
Upon joining, users curate a “rookery” of four birds to handle their messaging. Each bird mimics its real-world speed: a falcon is significantly faster than a hummingbird. For those seeking the ultimate slow-communication experience, the app even offers snails and turtles as delivery options. This gamified approach to correspondence transformed from a personal side project into a public phenomenon after a viral post on Threads highlighted users communicating in Elizabethan English via bird-speed delivery.
The response was explosive. Within three days of that post, the app’s user base ballooned from 10,000 to 100,000. Five weeks later, Roost is approaching 300,000 users, all drawn to the platform’s “wholesome” and “whimsical” nature.
Prioritizing Trust and Safety
Leveraging his professional background in trust and safety at Ticketmaster, Mendelsohn built privacy into the foundation of Roost. By default, the app only shares a user’s city. Precise location sharing is an opt-in feature reserved for “close friends.” Furthermore, the “Pen Pals” feature—which connects users with anonymous peers of similar age—includes strict warnings against sharing personal contact details. Currently, the app avoids photo sharing to ensure robust moderation tools are in place first.
Navigating the AI Art Controversy
Despite the app’s success, Mendelsohn faced significant backlash regarding his use of AI-generated art for the bird designs. Recognizing the community’s vocal stance, he has initiated a contest for human artists to contribute their work to the platform. While the transition from AI assets takes time and resources—particularly for a solo founder without external funding—Mendelsohn remains committed to the project’s growth.

“As a solo founder, I don’t think I could build and maintain something at this scale without AI-assisted development, but every product decision and direction for Roost still comes from me and the community,” Mendelsohn concluded.
