Bring a room onto your page in about ten seconds

Joining an audience tool can consume the fifteen seconds when you wanted a response. Some people mishear a spoken URL, type it incorrectly or miss the announcement. An account prompt adds another step for anyone who arrives. The moment you meant to measure may be over before the room is ready.

HeatCheck keeps the route short: one permanent address, a QR code for anyone who would rather scan and immediate anonymous voting. Joining requires no download, sign-up or email. The spoken address, visible link and scanned code all lead to the same page, so you do not need a separate joining workflow for each kind of audience.

One permanent address

Claiming a handle gives you heatcheck.io/your-handle as your permanent public address. It does not change between shows or include an episode number, and there is no per-show link to generate. Add it to a channel description, podcast feed, pinned post or business card once and leave it there. The same remembered handle works when you say it aloud, and the same saved link works for someone returning weeks later.

The same page follows the state of your show. Between shows, it says when you are next on. If you have launched a pre-show poll, it displays the question. Once you go live, it becomes the voting page. A listener who leaves the page open moves through those states without doing anything when the show starts. The address remains unchanged as the page moves from the next-show message to a pre-show question and then to live voting.

Say it, link it or show it

• Say it. A handle is short enough to read out and short enough to remember for the twenty seconds it takes to type. Spoken access works for an audio-only show.
• Link it. Channel description, episode notes, a pinned chat message. A visible link covers people who missed the announcement or arrived late. Because it is permanent, the same placement can stay in use from one show to the next.
• Show the code. On a lower third, a slide, or a card on a table. A viewer watching on a TV or second monitor can scan it with the phone already in hand, without reaching for a keyboard.

Sharp, spaced and camera-friendly

HeatCheck draws the QR as vector artwork instead of an image. The same artwork scales from a small corner widget on a 720p stream to a full-screen slide without blurring the module edges. It includes the standard quiet zone, the blank margin scanners need and many hand-made QR graphics omit. That spacing remains part of the code when it appears in a lower third, on a slide or on a printed card.

The code remains dark on a white tile, including on dark overlays. This is the exception to your selected theme because light-on-dark codes fail on a real share of phone cameras. A failed scan costs the viewer an attempt, and they do not try twice.

Anonymous voting on arrival

The interest slider appears ready to use. There is no onboarding, permission prompt or account gate. HeatCheck stores an anonymous token in the browser so one person with the page open on a laptop and phone does not count as two votes. That token is never connected to a name or email address. It provides browser-level vote deduplication without turning an anonymous response into an audience profile.

An account is relevant only to the two features that carry a listener’s identity between shows: roll call and the suggestions board . The prompt appears when they try to use one of those features, not when they enter. Someone who only moves the slider never sees a sign-up form.
