On the Analytics page, use the date range picker at the top of the dashboard to choose the period you want to look at:
Last 7 days — Recent performance snapshot (default)
Last 14 days — Two-week view
Last 30 days — Monthly overview
Last 90 days — Quarterly trend view
All time — Everything since your first quiz went live
Custom range — Pick your own from and to dates
All metric cards, trend charts, and the Quiz Performance table update automatically when you change the range. The comparison badges on each metric card compare your selected period against the period immediately before it.
You can also narrow the view with the device filter next to the date range picker — switch between All devices, Desktop, and Mobile.
The same date range and device controls are available on each quiz's detail page (open it via View details in the Quiz Performance table).
Note: the analytics summary on the app home page always shows the last 30 days. For other ranges, use the Analytics page.
