Create polls for your SharePoint site users to take. Votes are tabulated, and can be displayed either after the poll is complete or after the user votes.
Supports up to poll 4 options, and colors can be configured in the App settings. How votes are displayed is also configurable (vote count, percentage, or don't show).
Create a poll, and check "Is Open" to show it to your users. If you want to show results as they take it, check "Show Results" also. Otherwise, wait until you're ready to close the poll, uncheck "Is Open" and check "Show Results", and all users will see the results whether they've voted or not.
