Alternatives for adding a timer to a Google Form

Last reviewed 1 September 2026

Google Forms cannot time a quiz on its own, so every answer involves adding something. The options differ less in whether they work and more in where they run, which decides what they can do and what you need in front of you to set them up.

The options

Workspace add-ons

Add-ons such as Extended Forms (listed as "Timer + Proctor for Google Forms") and AutoProctor install from the Google Workspace Marketplace and run inside your Google account. Because of that they can read the form's response sheet directly and send mail as you, which is how they offer verified-email features and camera-based proctoring.

The trade is that they are browser tools. You set them up on a computer, and they require granting an add-on access to your Google account.

Apps Script

You can write a script that closes a form at a set time. Free, no third party, and entirely under your control — but it is a fixed closing time for everyone rather than a per-person countdown, and it means maintaining code.

A timed link

Instead of embedding a timer in the form, you share a link that carries one. Each respondent gets their own countdown starting when they open it, with the clock kept on the server so a reload does not add time. This is what AI Forms for Google Docs does, and it is set up from an iPhone rather than a laptop.

Which to choose

Everyone must finish by 5pm — a scheduled close. A per-person timer is the wrong shape for a shared deadline.
Everyone gets 30 minutes, whenever they start — a timed link.
You need camera or microphone monitoring — a dedicated proctoring add-on. That is a different category of product, with the privacy obligations to match.
You work from a phone — a native app, since the add-ons and the Forms editor both assume a desktop browser.

Worth being clear about what we do not offer: there is no camera monitoring, audio detection or screen recording here. Those need a respondent's webcam and microphone, and storage for the recordings — a serious undertaking with real privacy consequences, especially where the respondents are children. If that is your requirement, a dedicated proctoring product is the right answer.

Questions worth asking of any of them

Where does the clock live? A timer kept in the browser can be reset by reloading. One kept on a server cannot.
What happens when time runs out? Some tools can only grey the form out; submitting the answers requires the tool to own the page.
What does it store, and for how long? Ask specifically about IP addresses and any recordings.
Do respondents need to sign in? That decides whether limits can be enforced, and whether people without a Google account can respond at all.

AI Forms for Google Docs does this from your phone — no add-on, no laptop. Get it on the App Store.
