Would like to see a san-serif option, when enabling sound also flip the card to show it. Flicking left and right are nice but flicking up or down should also shuffle the card. The app crashed when reaching the end of the deck. Perhaps some stats at the end, common skipped, etc. Last feedback the chart should match the orientation of the device, should not need to rotate the device to see the chart, I know it’s in the tradition layout but very ux silly to rotate.
