Fetiphone

A phone screen is the whole interface here, and the four contacts on it exist for very specific, rather niche fetish scenarios, written out in full rather than left to your imagination. It reads less like a generic dating sim and more like someone had particular kinks and wrote around them directly.

You spend your time texting these four characters, buying them gifts, and playing a match three minigame to earn images, then using those images to manage their OnlySins page by deciding what gets posted. Everything you receive gets filed into a gallery you can revisit later, and you can pin any image as your phone wallpaper if you liked it enough. It's still an early alpha, so four characters and one minigame loop is currently the whole game.
