Line Dance Library is a simple, private home for the songs you dance to. Hear a song on the floor and want it? Recognize it, save it, and it's yours — with the title, artist, and album art already filled in. Then tag it the way you actually think about it: how hard is it, and have you learned it yet? RECOGNIZE WHAT'S PLAYING Tap once and Line Dance Library identifies the song playing nearby, then adds it to your library with its details ready to go. No typing, no guessing. ADD ANY SONG, INSTANTLY No music playing? Search for any song and tap it — the title, artist, and album cover fill in automatically. Or add one by hand and choose your own picture. TAG IT THE WAY YOU THINK • Difficulty — Novice, Intermediate, or Advanced. You decide. • Status — Yup, Practicing, or Nope. Honest, and only for you. JUMP STRAIGHT INTO THE MUSIC One tap opens the song in Spotify or Apple Music, so you can play it right now instead of hunting for it. KEEP YOUR REFERENCE VIDEO Attach the tutorial or demo video for any dance and it's one tap away when you're learning the steps. FIND ANYTHING FAST Search by title or artist, or filter by difficulty and status — see everything you're still practicing, or every Advanced dance you've conquered. SHARE A LIBRARY, KEEP YOUR PROGRESS Export your library to a file and send it to a friend — or import theirs. Your learning status never leaves your device, even when you share. Importing never overwrites what you already have; it only adds what's new. MADE FOR THE FLOOR A clean, quick design that looks right at home in dark mode for those late-night dance halls. PRIVATE BY DESIGN No accounts. No sign-in. No servers. No ads. No tracking. Your library lives on your device and nowhere else — because there's nothing to sign up for and no one to send it to. Built for the dance floor, and for one dancer in particular.
