The century-old continuous scale, running natively. Two anchors, a puck that slides between them, and a 0–100 score recorded automatically.
A visual analog scale is a plain line between two anchors: none of it on one end, the most imaginable on the other. The respondent marks the point that matches their experience. Psychologists were using it by the early 1920s, and it became a standard in pain and symptom measurement, where the shades between "moderate" and "severe" are the whole point. On paper it had one famous cost: someone had to measure every mark with a ruler.
Every answer lands as a 0–100 value the moment the respondent lets go. Scoring is automatic.
The puck moves smoothly between your anchors. Every position is a valid answer, not a disguised set of steps.
Alongside the score, PuckSurveys records how the answer happened: hesitation, revisions, and how decisively the puck settled. On paper, that information never existed.
Anchor wording is yours, so standard VAS items carry over unchanged. Responses arrive in real time on one shareable link, and respondents answer on whatever device they have. PuckSurveys is a survey tool, not a medical device: if you are running a clinical instrument, your protocol and ethics approval still govern how you use it.
Write your anchors, add your questions, share one link. About 3 seconds per answer, results as they come in.
