Get told what to fix before the next talk.
QR on your final slide. Attendees scan while packing up. You see the rating and the comments before you’re off the stage. Adjust your second talk that afternoon.
Q01Can I show results on my slides?
Open the results page on a second screen or browser tab. Updates live as votes come in. No refresh needed.
Q02Can I stop people from voting twice?
Not block them — votes always count. The only safeguard is a flag stored in the voter’s own browser that quietly skips the form if that browser already responded. It stops the casual double-submit, but anyone who clears their browser data or switches devices can answer again, so read the totals as a guide, not one-per-person.
Q03What if some attendees don’t have smartphones?
Most conference audiences are 95%+ smartphone. For the rest, pair them with a neighbor or skip them. The data is still useful.
Q04Should I create a new poll for every talk?
Yes. One poll per talk. Reusing polls across talks muddies your numbers.
Q05How many questions?
Three or four max. You get 45 seconds of attention while people pack up. One rating, one "what was useful", one open text.
Q06Does it work for a panel?
Ask about the panel overall, not each panelist. "Which topic mattered most" works better than rating four people on one poll.
