Timbre – An app that finds the best sounds for your sleep

In plain words

Timbre is an iOS app that helps users find which sounds improve their sleep quality by tracking the relationship between audio and sleep stages. Using machine learning and Apple HealthKit data, it analyzes which sounds lead to better sleep outcomes. Built by a solo developer, Timbre combines sleep sound selection with sleep tracking in a single application designed for iPhone users seeking to optimize their sleep through personalized sound recommendations.

In the maker’s words, at launch

Hey all, I'm currently a solo iOS developer who just released my first app, Timbre, onto the App Store (iPhone only for now). Here's a demo to show you how it works: https://www.youtube.com/watch?v=ALoPAFb31Bk. Timbre originally came about because I wanted to build a sleep sounds & sleep tracker app. I…

  I built a simple ambient sound app with no ads or subscriptions2025 · ambisounds.app · ▲314

  I’ve always liked having background noise while working or falling asleep, but I got frustrated that most “white noise” or ambient sound apps are either paywalled, stuffed with ads, or try to upsell subscriptions for basic features. So I made Ambi, a small iOS app with a clean interface and a set of freely available ambient sounds — rain, waves, wind, birds, that sort of thing. You can mix them, adjust volume levels, and just let it play all night or while you work. Everything works offline and there are no hidden catches. It’s something I built for myself first, but I figured others might…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
