Show HN: I built FlipCards – a flashcard app with variations to improve learning (flipcardsapp.vercel.app)

I took some time to put my before-sleep thoughts about true life costs in a simple browser only app. I don't know if this concept is unique, I didn't find anything else like it online, so I decided to make it.

It's an app that runs and saves stuff only in a browser locally, no external servers or services.

Hope you like it!
