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.

Pulse on Apple Watch

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.

1

Get your webhook

Pulse gives you a private URL for each number you want to watch.

2

POST your number

Send {“value”: 92, “label”: “Queue”} from anything that can hit a URL.

3

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.
