sumi just got a big, calm refresh. - A cleaner home with a quieter, more focused layout - Redesigned study flow: recall first, then reveal and rate - Tap once for dark mode, right from the home screen - A friendlier Getting Started guide built right in - Smoother, faster, and more reliable throughout As always: no account, no servers, nothing leaves your device.
