How it works

01

Connect

Pick a provider. Metrician reads your usage from the pages you're already signed in to.

02

Glance

Rings fill as you use. Hover one for reset time, pace through the cycle, and how fresh the reading is.

03

Make it yours

Drag it, resize it, switch skins, hide it on certain sites, or turn it off.

Privacy

Your provider data stays in Chrome.

Metrician reads allowance information from provider pages you connect and stores those readings in your browser. No extension telemetry.
