I'm building an app that allows users to take small self-assessments (more or less a quiz). The app doesn't require login credentials or a signup, as user progress is auto-saved (almost instantaneously) in local storage.
Currently the app will display a live point counter in the upper right that updates whenever a user creates/updates an answer.
During some initial user testing some users were concerned about whether or not the app was saving their work. How do I remedy this?
The site is still very much in beta, but here's a link so you can check it out first hand.
Edit (Jan 20, 17): Implemented a lot of the advice here including adding a saving indicator and changing some of the copy. Thank you all for the guidance
