■ 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." ■ Main Features 【Knowledge Classification System】 Simply sort words you know from words you don't, and it automatically creates a list of words to memorize. Focus your learning on unknown words efficiently. 【Sample Code for Every Term】 Every term includes sample code. Preview execution results to understand meanings visually. 【Review Function】 Repeated review helps programming vocabulary stick in your brain. 【Reverse Dictionary】 Quickly search for forgotten terms.

Learn progressively from beginner to advanced. 【Pronunciation Guide】 Learn how to pronounce terms like "width" and "height" for better workplace communication. ■ Supported Languages HTML / CSS / JavaScript / PHP / SQL / Laravel / Python and more Start memorizing programming vocabulary little by little every day!
