Turn any webhook into a shared push alert. Create an alert in Holler, share its invite with friends, then send a small JSON request whenever something important happens. Everyone who joined receives the same notification. Holler is useful for campground openings, ticket availability, home automations, server events, package updates, and anything else an existing script or service can detect. WHAT YOU CAN DO • Create private webhook-powered alerts • Invite friends with a link or join code • Add a sender avatar and tap destination • Mute an alert without affecting anyone else • Pause, resume, or rotate a webhook at any time • Send a test notification before connecting an automation SIMPLE BY DESIGN There are no accounts, feeds, ads, subscriptions, or notification-history screens. Private credentials stay on the creator’s iPhone, and alert events are retained only briefly for delivery. Holler is a lightweight, best-effort notification relay. Notification timing depends on Apple and device settings.
