Flashbang Protection
PROSwitching from a dark app straight into a blinding white one usually feels like staring into high beams. Our flagship, first-of-its-kind Flashbang Protection catches that spike the millisecond you switch, softens the blow, and glides brightness back up smoothly. For people who work at night, this is a lifesaver.
Built for the laptop lap and the three-monitor desk.
soonWhether you are using our active controls or upcoming tools like resolution presets and color sampling, everything is designed to behave identically on a solo MacBook screen and a full multi-monitor rig. Multiple monitor features are currently under development. Check out the roadmap.
One utility for your entire screen stack.
Instead of juggling separate apps to tweak brightness, grab colors, or manage displays, Phosphor is bringing the essentials under one roof. Check out the roadmap to see what's in store.
Built 100% natively in Swift for macOS with minimal background battery drain.
Everything is built for your own tweaking. I am actively building out the rest of the screen suite. Flashbang Protection is live now as the first Pro feature, with more on the way.

Nothing leaves your Mac.
Everything stays on your Mac. It is built with privacy at its core.
Built natively in Swift for macOS, not wrapped from a web app, which is why it stays light and doesn't drain your battery running in the background. Phosphor contacts our payment provider once when you activate a Pro license, and periodically afterward, only when online, to confirm the license is still valid. No other network activity.
