To give a bit of background:<p>I&#x27;m a full-time professional software developer, and I started this a couple years ago as a simple&#x2F;fast&#x2F;easy way to make flashcards for studying foreign languages.<p>Later enhancements focused on creating a teacher account role, which allows teachers to assign stacks of flashcards to students and watch the progress of their class in real time.<p>The app has been live for about a year, and successes with it include a law student passing the bar exam after using it for their exam prep.
