Dual-tier dimming
Drag in the center band: upper area adjusts hardware brightness down to the OS minimum; lower area keeps going with software dimming — perceptually darker than 1%.
Soft screen lamp
Pure Light turns your phone into a gentle, full-screen lamp — and keeps dimming below what iOS and Android normally allow. No flashlight glare. No clutter.
The problem
Most phones bottom out at 1% brightness — still too harsh for a dark bedroom. Pure Light uses a two-tier approach: first hardware brightness, then a soft canvas shift from white toward near-black. One natural drag. No overlays on other apps.
Features
Everything you need for a nightstand lamp. Nothing you don’t.
Drag in the center band: upper area adjusts hardware brightness down to the OS minimum; lower area keeps going with software dimming — perceptually darker than 1%.
Set a timer and Pure Light gradually dims to black — smoothly through both tiers. When done, the screen releases and your phone can sleep naturally.
One-tap presets — 1%, 10%, 30%, 65%, 100% — plus Resume last level. Open the app at exactly the brightness you want.
Tap the screen for a subtle action bar — Sleep Fade and optional Tip Jar. Drag to adjust brightness; tap alone never changes your level.
No account. No ads. No analytics. No permissions for the lamp itself. Your brightness settings stay on your device. Read our privacy policy.
Native on both platforms — lightweight, battery-conscious, and built with platform views, not bloated cross-platform frameworks.
How it works
Pure Light is intentionally minimal. The entire screen is the light source — no menus, no buttons cluttering your nightstand view.
