As you study with Synaptiq, statistics on your learning are calculated and presented on the Stats page.
Review Heatmap
The review heatmap shows the number of cards you've reviewed each day as well as cards due on future days. Green shades indicate that you studied at least one card on that day. Days with darker shades of green represent more cards studied than days with lighter shades. "Today" is represented by the circular day. Purple shades indicate cards due on days in the future. Hover a day to get information about the specific number of cards and the corresponding date.
