24 alternatives to I built an interactive cloth solver for Apple Vision Pro

A bit more context - the cloth sim is part of my app, Lungy (https://www.lungy.app). It's designed to be an active meditation / relaxation app, so you can play relaxing instruments in space and immersive breathing exercises. The original Lungy is a breathing app available for iOS, that uses real-time breathing with interactive visuals. The cloth sim is a Verlet integration, running on a regular grid. For now, I have tried a couple of different cloth scenes - a sort of touch reactive 'pad', where different parts of the cloth are mapped to different sounds and a cloth that blows…

    Hey HN! Some more info: I’m an NHS doctor and the founder of Pi-A (https://www.pi-a.io) which developed Lungy (https://www.lungy.app). Lungy is an app (iOS only for now) that responds to breathing in real-time and was designed to make breathing exercises more engaging and beneficial to do. It hopefully has many aspects of interest to the HN community – real-time fluid, cloth and soft body sims running on the phone’s GPU. My background is as a junior surgical trainee and I started building Lungy in 2020 during the first COVID lockdown in London. During COVID, there were…

    Hey HN! I’m an NHS doctor and the founder of Pia (https://www.piahealth.co) which developed Lungy (https://www.lungy.app). Lungy is an iOS app that responds to breathing in real-time and was designed to make breathing exercises more engaging and beneficial to do. It’s been two years since Lungy launched (here’s the original ShowHN: https://news.ycombinator.com/item?id=34534615) and it's had a huge update and complete redesign. We rebuilt the whole app, and added a real-time 3D soft body solver which gives some really cool interactions like blobs /…

    Squair▲162

    I built Squair because my phone was giving me anxiety - and it was also the only thing in my pocket when anxiety hit. The problem: 4 cups of coffee just to focus. Then the anxiety kicks in. Chest tight. Racing thoughts. Scrolling reels to "calm down" made it worse. I Googled "anxiety relief" at 2am and found box breathing — same technique Navy SEALs use in combat. First time I tried it, I felt the difference within 2 minutes. No crash. No pills. Just breathing. So I built an app around it. 6 months. Solo dev with a full-time job. 112 builds. 2 App Store rejections. Finally live. What it…

    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…

    I built a terminal app that paces slow breathing at 6 breaths per minute for vagal tone training. It's a single Python file, stdlib only, no dependencies — just run breathe and follow the bar. I'm a cardiology patient (HFrEF). Slow breathing at resonance frequency is one of the few non-pharmacological interventions shown to improve cardiac vagal tone and baroreflex sensitivity (Bernardi et al., Circulation 2002; Lancet 1998). I wanted a frictionless daily habit tool — no app store, no account, no subscription, just open terminal and go. Design constraints, all grounded in the clinical…
