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).

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…

Hello. I was looking for a simple and clean habit tracker. I went through a few apps but felt they were missing something. I also had some time on my hands, so decided to make my own and share it in case anyone else likes it.

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.

I had really bad health anxiety the last 2 years that severely impacted my quality of life. I started using Claude for support and was surprised by how much it helped. I realised how much potential there is for LLMs to provide an objective perspective on stressful thoughts - so I built an app that helps you form a habit around this to reduce long term anxiety. You vent what's on your mind and an LLM will evaluate your thoughts objectively (heavily leaning on CBT techniques), to help you maintain a more balanced perspective. Technical stack: - Flutter (to release cross-platform) - OpenAI API…
