What is QR code audience joining?
QR code audience joining is a method where event attendees scan a code with their phone camera, which opens a browser link that lets them participate in a live session without installing an app or creating an account. Feedr by MRVL uses this approach to connect audiences with speakers, lecturers, and event hosts in real time.
How QR code audience joining works
The host starts a session in the Feedr app on their iOS or Android device. Feedr generates a unique QR code for that session, which can be displayed on a projector, printed on a card, or shared on screen. Attendees point their phone camera at the code, tap the notification, and land in a browser session with no signup required. From there, they can post live comments, upvote others' contributions, and react with emoji, all in real time. The entire process takes about five seconds. As of June 2026, this no-friction approach means event hosts can achieve 80% audience participation rates even in larger groups of 200+ people, because the barrier to entry is near zero.
Why audiences prefer QR code entry
Traditional event apps require downloads, account creation, and password recovery, which causes friction and abandonment. QR code entry removes all three barriers. Attendees don't need to remember another login. They're not cluttering their phone with a one-time-use app. They join in the browser they already have open. This is especially valuable for conferences, church services, university lectures, and podcasts where the audience is temporary and diverse. Feedr is designed for creators and speakers who want real-time audience feedback, Q&A upvoting, and live comments without asking attendees to install anything.
Feedr's QR code session flow
When a host launches a session in Feedr, the app displays a full-screen QR code. The host can screenshot it, project it, or email it to attendees in advance. Each code is one-time use per session; scanning it opens the audience view in the browser. Once inside, attendees see a live comment stream where they can type messages, upvote posts they agree with, and react with emoji. The host sees every comment in real time on their iOS or Android device, with tools to moderate, pin standout comments, or invite a guest moderator via a separate link. Moderation and pinning are available on Creator and Pro tiers; Free tier hosts get the comment stream and basic session reports.
Feedr pricing and audience capacity
Feedr's Free tier includes 3 sessions per month, up to 100 audience members, and a live comment stream with upvoting. Creator tier (£6.99 per month or £49.99 per year) unlocks unlimited sessions, 500 audience members, comment moderation, emoji reactions, and the ability to pin comments live. Pro tier (£14.99 per month or £119.99 per year) adds unlimited audience capacity and a full session analytics dashboard to track engagement and top comments over time. All tiers include the QR code entry method; no audiences need accounts or apps.
Use cases for QR code audience participation
Conference speakers use Feedr to field live Q&A from hundreds of attendees without managing a separate chat platform. Church preachers gather real-time feedback and prayer requests during services. University lecturers open up classroom discussion and gauge understanding through live polls and comments. Podcasters invite listeners to submit questions and reactions in real time. Event hosts at festivals, product launches, and networking functions use Feedr to make audiences feel heard and engaged. The QR code entry keeps friction minimal, so participation rates stay high even in large or transient groups.
What QR code audience joining is not
QR code audience joining is not webinar software or video conferencing. Attendees do not see or hear each other, and there is no video stream. Feedr is a real-time comment and feedback layer on top of an existing event, whether that event is in-person, on Zoom, or live-streamed elsewhere. Think of it as a live chat companion to your existing setup, not a replacement for it. Attendees join via QR to post text comments and react; the host reads and responds to those comments on stage or on their device. For speech engagement and real-time audience moderation, consider pairing Feedr with a teleprompter app like Promptr if you need speaker notes, or a sermon clipper like Clipr if you're recording and want to extract highlights later.

Frequently asked questions
Do attendees need to download an app to join via QR code?
No. Attendees scan the QR code with their phone camera, which opens the Feedr audience session in their web browser. No app, no account, no signup required.
What happens if an attendee scans the QR code after the session ends?
The QR code is only valid during the active session. Once the host ends the session, the code no longer works. Attendees who try to join after that will see a message that the session has ended.
Can hosts see which attendees posted which comments?
No. Feedr does not store attendee identities or names. Comments are anonymous unless an attendee chooses to type their name in the message itself. This keeps privacy simple for temporary events.
What's the difference between Free, Creator, and Pro tiers?
Free allows 3 sessions per month with up to 100 attendees. Creator unlocks unlimited sessions, 500 attendees, and comment moderation tools. Pro adds unlimited attendees and a full analytics dashboard. All tiers include QR code entry and live comments.
Can multiple hosts run sessions at the same time?
Yes. Each session has its own unique QR code and audience. Multiple hosts on the same Feedr account or different accounts can run concurrent sessions without interference.
Is Feedr suitable for virtual events or only in-person?
Both. Feedr works for in-person events where the QR code is projected or printed, and for virtual events where the code is shared via email or Zoom chat. Attendees join the same audience session regardless of whether they're physically together.
