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…

Recording a video of the night sky results in extreme noise to the point that you don't really see anything, so I wrote a tool to significantly reduce noise in such video recordings. Essentially it computes a moving average across video frames which significantly reduces the random sensor noise. This works because aurora changes very slowly, and it's roughly comparable to a long exposure time computed out of a video file where the individual frames have a…

Hey HN, We've been working in neurotech over the past few years, primarily focusing on improving sleep. A friend asked if I would build her a vagal nerve stimulation device. These are devices used to improve relaxation, and “vagal tone”. She didn't want to shell out hundreds for the existing solutions. I originally said no, but then I thought, what if we leveraged smartphone haptics to achieve the same effect as these expensive devices? After some tinkering, Harbor: Immersive Calm was published to the app store last week. https://getharbor.app It’s pretty basic and very MVP, no…
