[Dev] Built a simple "5 Whys" app - Nazenaze-kun
A few years ago, my wife drew a short 4-panel comic with a character called "Nazenaze-kun" (in Japanese, "naze" means "why").
Later, I learned about the "5 Whys" problem-solving method, and the name clicked — so I built this little app around that idea.
It’s a lightweight tool that walks you through the "5 Whys" method:
- You type in something you're concerned about.
- The app keeps asking "Why?" five times.
- After the 5th why, it saves the whole chain in history so you can reflect later.
- You can also revisit past sessions from a simple menu.
Nothing fancy — just a tiny thought tool, but I found it surprisingly useful for self-reflection.
