Countdown timer for Google Forms
Google Forms has no built-in clock. Form Timer adds a live countdown bar to the top of any form, so a 30-minute quiz actually lasts 30 minutes and every respondent can see exactly how much time remains.
-
Start date windows for timed forms
Share the form link on Monday, but keep it sealed until Friday at 9:00 AM sharp. A start date keeps early birds out and guarantees the whole cohort begins together.
-
End date windows that actually close
A deadline that nothing enforces is a suggestion. Form Timer closes the form at the exact date and time you choose, so "due Friday at 5" finally means something.
-
Timing data in your Google Sheet
Every response gets three extra columns in your linked Sheet: when the person started, when they finished, and how long they took. Grading, shortlisting, and analysis happen where your data already lives.
-
Hidden timer for invisible tracking
Sometimes you want the data without the pressure. Hidden mode measures exactly how long every respondent takes while they see a completely normal, calm Google Form.
-
Anti-cheat validation for fair tests
Any timer that lives only in the browser can be beaten with a refresh. Form Timer Pro keeps the authoritative clock on the server, where respondents cannot touch it.
-
Auto-submit when time runs out
When the countdown hits zero, the response submits itself. The time limit stops being a polite request and becomes how the form actually works.
-
Welcome page and custom instructions
The clock should not start while people are still reading the rules. A welcome page briefs respondents first, and the timer only begins when they click start.
