Breathing training halo

Breathing training halo turns your screen into a calm, breathing glow — a minimalist companion for relaxation, focus, and sleep. No audio cues, no complicated charts. Just light that rises and falls with your breath. Breathe with the light A full-screen gradient slowly brightens, holds, then fades, following a smooth sinusoidal curve. Tap anywhere to open a lightweight control panel for brightness and color; tap again to dismiss it and let the light keep breathing. Find your rhythm Choose the classic 4-7-8 sleep technique (4s in, 7s hold, 8s out), a quick Focus pattern for work breaks, or build your own cycle with individual inhale, hold, and exhale sliders. A live visualizer shows the current phase and remaining seconds so you can feel the rhythm before you commit to it. Twelve curated gradients From Cyberpunk magenta to Deep Sea blue, Campfire amber to Aurora green — switch between twelve hand-tuned presets with a smooth cross-dissolve. Override True Tone and Night Shift to see colors exactly as designed. Care for your display Pixel shifting subtly moves the gradient to reduce burn-in risk, ambient dimming lowers the glow in dark rooms with a configurable minimum floor, and a one-tap Screen Wash cycles red, green, blue, and white at full brightness with a countdown ring to help clear image retention. Smart power automation See battery level and charging status at a glance, then let the app react: auto-start when plugged in, sleep after unplugging, stop breathing below a battery threshold (20% by default), or keep the screen awake. All settings are saved automatically. Dark, distraction-free, and designed for the moments when you just need to slow down.
