Ever wished Spotify or Letterboxd had a dating mode? Meet people who share your niche cultural taste. Most dating apps ask about broad interests like “movies,” “music,” or “travel.” But those labels say very little about who someone really is. What creates real alignment are the specifics — the particular film by your favorite director that you can rewatch endlessly, the novel you still think about years later, the album you always return to, or the place you like to go because the people there somehow feel like your kind of crowd. When two people genuinely care about the same films, books, music, or places, meeting tends to feel smoother and more natural. There’s less guessing, fewer mismatches, and fewer moments of wondering whether you’re really on the same wavelength. Shampoo was built for those kinds of connections. Instead of endless swiping, your specific cultural tastes do the filtering first. Every day, you’ll meet two people who share your taste — so when you start talking, it already feels like you’re coming from the same place. --- Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
