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…
- EBEvery Breath You Take – Heart Rate Variability Training2023 · github.com · ▲348
Through controlled breathing it is possible to regulate your body's stress response. I've built an app to measure and train this effect with a Polar H10 Heart Rate monitor. With every breath you take, you can set the pace of your breathing rate, measure your breathing control with the chest accelerometer, and see how heart rate variability responds.
- LBLive breath detection and biofeedback from a phone microphoneJun 2026 · github.com · ▲67
Hi everyone, I am Felix, a famliy doctor from ZH, Switzerland. A couple of month ago I started this little project called shii • haa, a breathing app that uses the phone`s microphone for live biofeedback My prior work in emergency medicine and intensive care was closesly linked to breathing, mostly in critical situations... and let me to reevaluate my own way of breathing. over time one question popped into my mind: can medical knowledge and biofeedback make an app actually promote self-awareness instead of attaching your goals to the award system of the app. it combines signal processing, a…
- DTDon't Hold Your Breath – Breathing Analysis with Polar H10 HR Monitor2023 · github.com · ▲51
A person's heart rate fluctuates based on factors such as activity, environment, and mental state. Additionally, heart rate variations occur on a much shorter timescale, with changes happening every few seconds. During inhalation, heart rate slightly increases, and it decreases again during exhalation, a phenomenon known as respiratory sinus arrhythmia. There are several reasons for this. Firstly, an increase in volume within the thoracic cavity (the space between the ribs) leads to a corresponding drop in pressure, which is counteracted by a rise in heart rate to regulate blood pressure.…
- AWApple Watch app with haptic-guided breathing to help you meditate2025 · apps.apple.com · ▲6
I've been interested in meditation for many years now. Worked at meditation startups, have done Vipassana 10 day retreats. I've been able to get into some pretty deep meditation sessions and those have always been nice for me. But for whatever reason, it always felt like playing the slot machine for me. I could never consistently get into the space. Meditation kind of would come and go in my life. Anyways, I stumbled across this guy on Youtube talking about HRV resonance meditation (i'll link him below, but i'm not affiliated). He talked about reaching this meditative state as being a…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
