■ Born from the thought: "If only I could learn programming like flashcards..."

When I was learning programming, no matter how many video tutorials I completed, I couldn't write programs well. The reason was that programming "vocabulary" wasn't sticking in my head.

"How do I write a loop again?" "What's the function to get the first 3 characters of text?" I wasted so much time searching through tutorials repeatedly.

So I started writing everything I learned into flashcards and memorizing them for 30 minutes daily. In about 2 months, I could write simple programs fluently. From this experience, I developed Pro-Tan as "the app I truly wanted 5 years ago."
