Corelly turns a single button press into a moment of connection. Place a Corelly button on a table, a desk, a nightstand, or any flat surface in your home and let your loved ones know it's time to gather. Press the button to call everyone for dinner, signal bedtime, or remind the kids it's homework time. Whoever is in your family group instantly receives a notification on their device, wherever they are in the house. KEY FEATURES • One-tap notifications: Press the physical Corelly button to instantly notify your entire family group. • Custom messages: Personalize what each button sends, from "Dinner is ready" to "Time for bed" to anything you want. • Real-time delivery: Notifications arrive in seconds via secure push. • Family groups: Create or join a family with a simple invitation link. • Notification history: See every press, who saw it, and when. • "Seen" acknowledgments: Confirm you've received a notification with a single tap from the lock screen. • Multiple buttons: Manage as many Corelly buttons as you need from a single app. • Secure setup: Configure each button via Bluetooth in under a minute, then it connects to your Wi-Fi automatically. HOW IT WORKS 1. Create your family group in the app, or join an existing one through an invitation link. 2. Pair your Corelly button via Bluetooth, the app guides you step by step. 3. Place the button on any flat surface in your home. 4. Press the button. Everyone in your family gets notified instantly. WHO IT'S FOR • Families coordinating daily routines: meals, bedtime, homework, departures • Households where everyone is in a different room • Couples and roommates organizing shared spaces • Anyone who wants a simple, physical way to reach the people they live with PRIVACY FIRST Corelly only stores what's needed to deliver your notifications. No tracking, no advertising, no data sold to third parties. Your family group is private to its members. Note: At the moment, Corelly requires a physical Corelly button to send notifications. The ability to send notifications directly from the app may be added in a future update.
