Relay turns a spare iPhone or iPad into a hands-free Shortcuts trigger. Run any Shortcut on a repeating interval or at specific times of day, or fire it from another device on your Wi-Fi with a simple, token-protected local web request. No subscription. No account. No cloud. Everything runs on your device and your local network. WHY RELAY Some automations only work when a device actively opens an app or runs a Shortcut — showing a camera dashboard every few minutes, rotating a status display, kicking off a sync, opening a kiosk app on a timer. iOS only allows an app to launch Shortcuts while it is in the foreground, so Relay is built to be exactly that: a reliable foreground scheduler you leave running on a dedicated device. SCHEDULER • Unlimited rules, each with its own Shortcut, interval (from 1 minute) or list of exact times • Optional active window per rule (e.g. only 8:00–17:00), overnight windows supported • Wall-clock scheduling: if a fire time passes while the schedule was paused, Relay catches up the moment it becomes active again • Live countdown to the next trigger, per rule and overall LOCAL NETWORK TRIGGER • Built-in HTTP endpoint on your Wi-Fi: GET /run?shortcut=Name — from a laptop, home server, Raspberry Pi, or any browser • Token-protected (query token or Bearer header), with one-tap token generation • Bonjour advertising (_relay._tcp) so other devices find the phone even when its IP changes • /health and /next endpoints for monitoring and scripting, plus a built-in status web page • Foreground-only and LAN-only by design — nothing is ever exposed to the internet KIOSK ESSENTIALS • Keep-awake (never lets the screen sleep) while active • Stall detection: if another app kept focus and the loop stopped, Relay shows a one-tap resume banner and can notify you • Battery level and charging state on screen, with Guided Access guidance for true kiosk setups • Live event log of every trigger, request, and state change EXTRAS • Home-screen widget with the next trigger and last run • Live Activity countdown in the Dynamic Island while the schedule runs • Diagnostics page: foreground state, listener state, address, recent triggers • Step-by-step onboarding that builds your first automation loop with you Relay is 100% free — every feature, forever. It runs the Shortcuts you created, and it never collects any data.
