Tap Relay

Press the button. Fire the webhook. That's it.
Tap Relay turns your iPhone into a portable bridge between a Flic Bluetooth button and any HTTPS webhook endpoint. Press the button, the phone fires a POST, your backend gets the event. No hub required. Works wherever your phone works.
Setup is one QR scan.
The official Flic app makes you type webhook URLs on a phone keyboard, hand-format JSON headers, and navigate deep menus to wire everything together. One typo and the whole thing silently breaks.
Tap Relay does it differently. Your endpoint provider generates a QR code with the webhook URL, auth token, and button binding pre-configured. You scan it. You're done. Setup time: under five seconds.
Built to survive the background.
Most webhook apps die quietly when iOS gets aggressive with memory. Tap Relay uses Core Bluetooth State Restoration and background URLSession the way Apple intended — so even if the app gets evicted, the next button press wakes it up and fires the webhook anyway.
Lightweight, single-purpose, no consumer-app bloat. Behaves more like a system daemon than an app.
Made for the people who need it most.

Developers wiring Flic buttons into Zapier, Make.com, Home Assistant, or their own PWA
Mobile professionals — field techs, real estate agents, delivery drivers — who need the button to work away from home, not just inside HomeKit range
SaaS platforms shipping pre-provisioned hardware to non-technical end users
Anyone who wants a clean, reliable, single-purpose alternative to the official Flic experience

Fire HTTPS POST requests on press, double-press, and hold events
Background-survivable BLE via Core Bluetooth State Restoration
