Open Chambers

Know how your reps vote.

Enter your ZIP code. Follow your representative and senators. Get a notification, with a plain-English official summary, every time they vote.

Try it on the web

Free. No account. No tracking. Made by John Hubert LLC.

How it works

Three steps, under a minute.

Enter your ZIP

The app looks up your congressional district from a table on the phone and shows your representative and both senators. The ZIP never leaves your device.

Follow anyone

Flip the switch next to a member. Choose "Final passage" for the votes that decide a bill, or "Every roll call" to include amendments and procedure.

Get the alert

As soon as the official record posts: how they voted, the result, and a one-line summary from the Congressional Research Service. Tap through for every member's position.

Where the data comes from. Roll calls from the U.S. House Clerk and the U.S. Senate; member records from the unitedstates project; ideology scores from Voteview (UCLA); bill summaries from the Congressional Research Service via Congress.gov. Every vote links to its official page.

What we store. If you turn on alerts: an anonymous notification token and the members you follow. That's all, and it's deleted when you unfollow them.

Questions

Is it really free?

Yes. There are no ads and nothing to buy. If you'd like to support the work, there will be a way to leave a tip in a future version.

Does it tell me how to vote, or who's right?

No. Open Chambers shows the record and nothing else. The one measure of ideology it shows, DW-NOMINATE, is a published academic method and is displayed exactly as its authors publish it, with a link to how it's calculated.

Why don't I get an alert for every vote?

By default the app sends alerts for final-passage votes only, because most Senate days consist of procedural votes and nominations. Switch to "Every roll call" in Settings if you want all of them.

Android?

Not yet. The web version works on Android and can be added to the home screen; an Android app is planned.
