Pulse · Apple Watch
One number that matters.
Always on your wrist.
Point Pulse at a value with a tiny webhook and it appears on your watch face — on-call status, a KPI, a price threshold — updated the instant it changes via server push. No polling, no app to open.
Features
Your number, ambient and current.
Push-fed widget
A single number, label, trend and colour — updated the moment it changes, via server push.
Webhook ingest
You get a unique URL. POST a value and your watch face updates. That's the whole setup.
Threshold states
Green, amber and red bands with an optional haptic the moment a state flips.
Multiple channels
A few independent numbers — Queue, Revenue, p95 — each its own widget.
How it works
Three steps, then it's just there.
Get your webhook
Pulse gives you a private URL for each number you want to watch.
POST your number
Send {“value”: 92, “label”: “Queue”} from anything that can hit a URL.
Watch it on your face
It lands on your complication and stays fresh — no polling, no battery drain.

FAQ
Quick answers.
How does it update so fast?
Pulse uses watchOS push to update the widget the instant your value changes, relayed by Zen Labs' own edge — not background polling.
Is there a subscription?
No — a one-time purchase for the app and your personal channels.
What can I push?
Any webhook-able number: on-call status, a KPI, queue depth, a price threshold, a health check.
