Use case
Survey timing analytics
How long people take to answer is data your survey is currently throwing away. Form Timer captures completion time for every response, with or without a visible clock.
Duration is a data-quality filter
A 45-second completion on a 10-minute questionnaire is almost certainly straight-lining. Sort the duration column in Sheets and screen out low-effort responses before they skew your averages. Researchers do this routinely; now your Google Form supports it.
Find the questions that cause friction
If median completion time is triple what you promised in the invitation, respondents are struggling, and your drop-off rate is paying for it. Real timing data tells you when to cut questions, simplify wording, or split the survey in two.
Measure without changing behavior
Hidden mode records timing while respondents see an ordinary, unpressured form. No countdown, no stopwatch effect, no rushed answers. The measurement stays invisible so the data stays honest.
Analyze where your responses already are
Timing fields land in the same spreadsheet as the answers. Join duration with any question, pivot by segment, or chart completion time across survey versions. If you can do it in Sheets, you can do it with this data.
