The Geiger device: a small white desk cube with an AMOLED screen showing 59% current usage resetting in 2h 54m and 16% weekly usage resetting in 4d 17h.

The Problem

Your limits are invisible until you hit the wall.

Heavy users get two overlapping limits and no warning. You either pace too conservatively and waste capacity, or run out mid-task and waste time.

No Warning

Nothing tells you you’re close until you’re cut off mid-thought.

No Glance

Checking means breaking flow to dig through a dashboard.

No Feel

You never build intuition for your own pace. Geiger gives you one.

On Your Desk

Designed to be glanced at, never fiddled with.

It just sits there and glows. Colour shifts from lime to amber to coral as you get close — you feel “running low” without reading a single number.

How It Works

Runs on your machine. Private by design.

A tiny background program on a computer you already keep on reads your own usage and sends just the numbers to the device over your home network. No cloud, no account.

STEP 01

Set Up Once

Authorise it with your own access token. A couple of minutes; no passwords stored.

STEP 02

It Watches Quietly

Every few minutes it checks your current and weekly usage in the background.

STEP 03

You Just Glance

Two bars and a reset countdown. Colour shifts as you get close. That’s it.

A pixel-accurate on-screen simulator is included, so you can run the whole system today.
