Sleep sounds that don't cost $70/year | Drowze

Hey everyone — I'm Jacob, the solo dev behind Drowze. Happy launch day. I've been staring at this for three months and I'm genuinely excited to finally show it to people. The reason I built this: I was paying $70/year for a sleep app that played one sound at a time. I wanted to mix brown noise and rain together and couldn't figure out how without buying a premium subscription. That seemed insane to me. So I spent a weekend prototyping a basic mixer in SwiftUI, and then it kind of snowballed from there. The thing I'm most proud of technically is the audio engine — I'm using AVAudioEngine with seamless loop scheduling so there's literally zero gap at the loop point when sounds repeat. Took me about two weeks to get right. The other thing I dig is the night light: it uses specific wavelengths (like 660nm deep red) that sleep science suggests don't suppress melatonin the way blue light does. Genuinely didn't know that was a thing before I started researching this. Free tier gives you 21 sounds, 3-track mixing, the timer, and breathing exercises — I tried to make it generous enough that you'd actually want to use it before ever seeing a paywall. If you want to try Premium: I'm giving away promo codes to the PH community today. Drop a comment and I'll send one over. Honest question for the thread: what actually helps you fall asleep? I've heard everything from "total silence" to "8 overlapping rain tracks." Curious what's working for people.
