Opiner is an app that allows users to quickly test ideas and gather opinions from a diverse range of people. It is seen as a tool to determine if an idea is good or how people might respond to it. Unlike social media, Opiner provides less polarized opinions and allows for a more balanced view. It can be used to test theories, such as government instructions on social distancing, and see how different people interpret information. Opiner can also be used as an alternative to focus groups, gathering responses from a wide range of individuals. Users find it valuable as it allows for quick brainstorming and opinion-sharing, providing insights that may not typically be explored in their everyday lives or jobs. The app can be beneficial for any brand, regardless of whether they have a physical product, as it taps into the opinions of the semi-intelligent general public.
