Last year I had my first real panic attack. Heart racing, couldn't breathe, thought I was dying. The ER doctor told me it was anxiety and suggested breathing exercises.
I tried following YouTube videos but they were hard to use during an actual panic attack — too much talking, couldn't focus. So I started building a simple app that just shows you WHEN to breathe with a visual guide. No talking, no complicated UI, just breathe in... hold... breathe out.
It took me months but it actually helped me. The 4-7-8 technique before bed changed my sleep completely, and box breathing gets me through stressful days.
I ended up publishing it — it's called Lunair if anyone wants to try it. Free to use, no account needed.
But honestly, even without any app — just try the 4-7-8 method tonight before sleep. 4 seconds in, 7 seconds hold, 8 seconds out. It sounds too simple but it works.
