I kept forgetting every Spanish word I studied on flashcard apps. But lyrics from songs I liked? Those stuck for months without trying. That's not just me — research shows music encodes vocabulary through melody and rhythm in ways repetition can't match. So I built an app around that. Turtle Tune has two parts: 1. Learning path - original songs organized by topic (greetings, food, travel, family). Each one teaches specific vocabulary at A1-B1 level. 2. Real songs - Bad Bunny, Shakira, Maluma with karaoke lyrics and translations. Because understanding what's on the radio is half the motivation. Every song: line-by-line karaoke highlighting, tap any word to translate, slang cards for street Spanish, and a 3-step quiz to lock it in. Solo dev, live on iOS. Would love to hear: what Spanish song would you want to learn first?
