A paywall survey asks people who looked at your subscription and said no what held them back. This template takes about 30 seconds: the reason they didn't subscribe, the plan they were considering, and a fair monthly price in four bands, so you can tell a price problem from a trial problem or a doubt about value.
It is written for the second time someone closes the paywall, when the no is deliberate. In a web app, fire a custom event each time the paywall closes and set calls needed to 2, so the survey opens on the second dismissal (from Starter, or on 1 survey on Free). Inside a phone app, have the app open the survey's link at the same moment, with the paywall version added to the link as a tag.
Results shows a donut for each question with the share and count of every answer, typed Other reasons listed beside the first, against the period before. Select The price to filter the whole page and see which plan and which price band those people picked. Usertick reads every typed reason and files it under a category such as pricing and plans.
