Drowse - Sleep Sounds
A simple sleep sounds app that just works™ and doesn't have ads.
White noise helps me fall asleep. The app that I was using for years added ads, which is weird for something as simple as this.
So I made my own and it's intentionally simple: five sounds and a play button. Design was done by a Stitch and Gemini 3.0 tandem, with some minor modifications by Opus 4.6. Coding was done by Opus 4.6 and GPT 5.4.
It's my first rodeo into publishing Android apps, and €25 and a lot of verification steps later, it's live on Google Play.
In terms of audio, Pixabay had a bunch of royalty-free sounds that did the job pretty well. One exception was the standing fan noise. I couldn't find one that looped well and provided steady noise. They were all either low quality, or had annoying clicking noises. Turns out Opus is pretty good at sound generation and I ended up just generating one. I don't think I'd be able to differentiate between that and a real-life fan in a blind test. The Pixabay downloads all had different loudness levels so I normalized with ffmpeg, and also trimmed the start and finish slightly to make it loop more fluidly.
It's translated into 11 languages, also via Claude.
