   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…

   Every Breath You Take – Heart Rate Variability Training▲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.

    Breathe CLI – Paced resonance breathing in the macOS terminal▲132

    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…
