Built for iPhone Duo, not stretched onto it.
Every view in Everkin works on both of iPhone Duo's displays. Folded, it's the phone you know, with navigation in the system's vertical bar. Open, screens split into two columns, and partly folded, the gap between them sits right on the hinge. Arriving with iPhone Duo.
In App Store review. Every iPhone from 13 mini to Pro Max keeps its current layout.
Folded. The cover display, navigation in the vertical bar. 
Open. Two columns on the inner display. 
Partly folded. The columns meet at the hinge, never across it.
What changes on iPhone Duo
Every view, both displays
Nothing falls back to a stretched phone layout. Dashboard, Pets, Care, Visits, Family, and every screen inside them were reworked.
Two columns that respect the hinge
Related information sits side by side, and when the device is partly folded the gap between columns lands on the hinge, so no card is cut by the fold.
Native on the cover display
Navigation and toolbar actions move to the system's vertical bar beside the camera, so content keeps the full screen.
Your colors, on both screens
Everkin ships 30 themes, six of them free. Each one recolors the whole app, cover display included.

About Everkin
Everkin is your pet's whole story, always with you. It keeps health records, daily care, and everyone who loves your pet on the same page, so a pet's whole life lives in one place instead of scattered across group texts and notebooks. Built for multi-pet households and pets with real medical complexity, it holds medications, vet visits, weight trends, glucose, seizures, symptoms, and daily wellness on one shared timeline.
Everkin is operated by Ghost Labs LLC, a New York company founded in 2025. The iPhone app is available now and is free for up to two pets; Everkin+ unlocks unlimited pets, household sharing, advanced analytics, and PDF exports. Caregiver access for pet sitters is always free.

Founder
Corey Schaf
Founder
Corey has been building software for 20+ years, from messing around with C compilers as a kid to shipping games, mobile apps, and SaaS platforms as an adult. A University at Buffalo grad, he has worn a lot of hats along the way: founding engineer, team lead, architect, and founder a few times over.
In 2025 he founded Ghost Labs to build whatever brings joy, no trend-chasing, no roadmap theater, just engineering for the fun of it. The goal isn't to be everywhere. It's to make a small dent in the world and have a good time doing it.
