Audience response systems
Almost every audience response system is now a phone in the room.
It used to mean a box of keypads handed out at the door and collected at the end. The job has not changed. Ask a room something, show the answer immediately. What changed is the hardware, and at its best the question is now a slide in the deck you were presenting anyway.

What is an audience response system?
An audience response system, or ARS in the procurement documents where the older term survives, lets everyone in a room answer the same question at once and shows the combined result straight away. That is the whole definition. The reason it matters is narrower than it sounds: it replaces the show of hands, which is slow, publicly visible, easy to miscount, and quietly biased by whoever raises their hand first.
The category has had three distinct generations, and most of the confusion about what to buy comes from people comparing products from different ones.
Three generations
Keypads, then a second screen, then the slide itself.
Each generation solved the previous one's real problem, and each introduced a new one. Knowing which generation a product belongs to explains most of its design decisions.
Hardware keypads
Physical clickers handed out at the door and collected at the end. Reliable, controlled, and independent of the venue's network, which is why a handful of lecture halls and certified training rooms still use them. The cost is inventory, batteries, distribution, and an answer set that stops at A to E.
The web app
The phone replaced the keypad, and typed answers became possible, which is where word clouds and open-ended questions come from. The new problem is structural. The tool is a second application running next to your deck, so every interactive moment means leaving the presentation and coming back.
Inside the presentation
The activity is a slide. The audience still answers on a phone, but the presenter never switches windows, because the question and its results live in the deck alongside everything else. This is the generation Decka is built for, and it is what the rest of this page compares against.
How to evaluate one
Six questions that decide this, and none of them are feature counts.
Every product in this category can put a bar chart on a screen. These are the things that actually differ, roughly in the order they tend to stop people.
What does the free tier cap?
Not how much it costs. What it limits. Audience size, questions per presentation, and sessions per month are three different ceilings, and the one that hurts depends on whether you run one large event a quarter or a small session every week.
How does the audience get in?
A short code or a QR into a phone browser is the standard, and anything asking for an app or an account will cost you a visible fraction of the room. In a large venue, ask separately what happens when the Wi-Fi cannot carry everyone.
How many windows does it take?
Running the activity from inside your slides rather than beside them sounds like a detail until the fourth interactive moment of a ninety-minute workshop. Count the switches rather than the features.
What does anonymous actually mean here?
Not shown on screen and not recorded at all are very different guarantees. For a psychological-safety check or a contested decision, only the second is worth having, and it is a question to settle before the session.
Where do the answers go afterwards?
Some sessions end when the slide changes. Others need a report, an export, or a record that survives the meeting. If yours is the second kind, look at the reporting before you look at the polling.
Which question types do you actually need?
A multiple-choice poll, a word cloud, a moderated question queue, a competitive quiz and a ranked list are five different tools for five different moments. Most products are excellent at two of them and adequate at the rest.
How it works
- 01
Add it to your slides
Drop the activity into your deck — in the Decka editor, PowerPoint, or Google Slides.
- 02
Audience joins by QR
Everyone scans and answers in their phone's browser. No app, no account, nothing to install.
- 03
Results live on the big screen
Responses land on your slide in real time, in front of the whole room.
The tools people actually compare
Two products dominate the shortlists, for different reasons, and the honest comparison of each is its own page. Both list ten options with the trade-offs stated, ours included.
Where Decka sits in this
Decka is a third-generation tool, and it comes at the category from the other end. It is a full presentation editor, with a freeform canvas, layers, frames, charts, themes and real-time collaborative editing, that has the audience layer built into it rather than a response tool that grew some slides. The poll, the quiz, the word cloud, the Q&A and every other activity type are objects you place on a slide you designed. 16 types in all. 15 of the 16 run inside PowerPoint and Google Slides; Bingo is built in Decka's own editor, because its content is bound to specific slides. The audience joins the way they would with any modern system, using a short code and a phone browser with no app and no account, but the presenter never leaves the deck.
That is a real trade-off rather than a strict improvement, and it is worth being direct about which side of it you are on. If you want a standalone polling tool with no relationship to your slides, a second-generation product is a better fit and this is the wrong shape. If your interactive moments keep interrupting a presentation you have already built, that interruption is the problem this generation exists to remove. See what each activity type does.
FAQ
Audience response systems, answered
What is an audience response system?
An audience response system, or ARS, lets everyone in a room answer a question at the same time and shows the combined result immediately. It began as a set of physical keypads handed out at the door. Today it is almost always a web page the audience opens on their own phone, with results appearing on the presenter's screen as votes arrive.
Do audience response systems still use clickers?
A few settings still do. Some university lecture halls and some certified training environments need a controlled device rather than whatever is in somebody's pocket. Everywhere else the phone replaced the keypad, because it needs no inventory, no batteries and no distribution at the door, and because it can accept typed answers rather than only a letter from A to E.
What is the difference between an audience response system and a polling app?
In practice, none. They name the same category from two eras. "Audience response system" is the term that survives from the hardware period and is still standard in higher education, healthcare and conference production. "Live polling" or "audience engagement" is what the same products call themselves now. If a procurement document says ARS, a modern polling tool is what it is asking for.
How many people can an audience response system handle?
That is the limit worth checking first, because it is usually what stops you rather than any feature. Up to 50 participants per live activity on the free plan, 150 on Pro, and 300 on Badass. Other tools cap by audience size, by questions per presentation, or per event, and which of those hurts depends entirely on whether you run one big session a quarter or a small one every week.
Can responses be anonymous?
With most tools, yes, and it is worth confirming what anonymous means in each one. There is a real difference between results that are not attributed on screen and results that are not attributable at all in the report afterwards. For a psychological-safety check or a vote on a contested decision, the second is what you need, and it is a question to ask before the session rather than after.
Do audience response systems work without Wi-Fi?
Most need a data connection of some kind, though a phone's mobile data is usually enough. Large venues are the real risk. Several hundred phones joining one congested network at once is a common failure, so if the room is big and the network is unknown, ask each vendor what happens in that case before you commit to one.
