Foyer - Spatial ambient sound rooms, now on iPhone

Hey Product Hunt, I'm back. I launched Foyer for Mac here last month. The most common reply by far was "I need this on my phone." So here it is: Foyer for iPhone. Foyer turns ambient sound into a place. You sit at the center of a black canvas as a point of light, and each sound is a glowing orb you drag around yourself with your thumb: a crackling hearth, rain, a stream, a distant city. Pull one closer and it swells. Slide it left or right and it pans there. It's real binaural spatial audio, so with headphones on you're sitting inside the room. AirPods head tracking keeps the field anchored as you turn your head. I built it for focus and for winding down at night. There's a sleep timer that fades the room out gently, and lock-screen and Control Center controls so you never need the app open. No account, no ads, nothing collected, ever. It's free to use with up to three sounds in a room. One purchase unlocks unlimited sounds and rooms, and since it's a universal app, that one purchase covers both Mac and iPhone. No subscription. If you already bought it on Mac, the iPhone app is yours at no extra cost. Just tap restore. I'd love to know which room you'd build first, and what sound is missing for you. I'm here all day.
