Softens the brightness jump when you switch to a bright window.

Switch from a dark app to a bright window and the screen can jump to full brightness all at once. Flashbang Protection softens that jump, then eases back to normal. It works when you switch apps with a Dock click or Cmd+Tab, switch desktops, or use Mission Control and App Exposé. Part of Pro.

It does not cover brightness changes inside an app, like switching tabs.

Needs Input Monitoring. Without it, Flashbang Protection does not run.

Pro is a one-time purchase of $19.99. It includes Flashbang Protection and five Studio features. Ring Light is coming soon. Future major upgrades may be offered at a reduced price to existing Pro owners. One license key works on one Mac. Replacing your Mac? Contact support and we'll reset it.

Future upgrades are planned in good faith as part of active development. If a planned feature doesn't ship, this doesn't entitle you to a refund beyond the standard 14-day guarantee.

Every feature here, Pro included, is being continuously refined based on real usage and testing.

Installation Steps

  1. Open the downloaded .dmg file.
  2. Drag the Phosphor icon into the Applications folder.
  3. Open System Settings and grant Screen Recording, Accessibility, and Input Monitoring.

Requires macOS 13 or later.

Required Permissions

macOS requires explicit permission for display utilities to function. Here is exactly what Phosphor uses them for:

  • Screen & System Audio Recording (Screen Recording): Allows Phosphor to access the screen information it needs for its display features. Nothing is recorded, stored, or transmitted. A screenshot you take is copied to your clipboard and is not saved to disk. Phosphor does not access your audio. Used by Flashbang Protection (it reads how bright your screen is), Screenshots and Color Picker.
  • Device Control & Data Access (Accessibility): Allows Phosphor to work with macOS and your displays using the system access required for its features. This access is processed locally and is never used to collect or share your personal data. Used by Flashbang Protection, to see what a click on the Dock or in Mission Control landed on. Without it, those switches are not recognized.
  • Input Monitoring: Allows Phosphor to respond to the system input it needs for its features. Input is processed locally, Phosphor does not record or store what you type, and nothing is transmitted. If you turn on Keystroke Display, the keys you press are shown on screen. Used by Flashbang Protection, to see Dock clicks and Cmd+Tab, and by Keystroke Display. Without it, Flashbang Protection does not run.

Phosphor never requests Camera, Microphone, Contacts, or Location access.

Questions

What do I need?
macOS 13 or later.
Which permissions does Phosphor ask for?
Screen Recording, Accessibility and Input Monitoring. The list above says what each one is for.
Does it work offline?
Yes. A Pro license needs an online check at least once every 7 days.
How many Macs can I use?
One Mac per license. Replacing your Mac? Contact support and we'll reset it.
Do updates install on their own?
Phosphor checks once a day and always asks first. You can turn it off in Settings.
Which permission does each tool need?
Laser Pointer, Drawing, Flashlight, Soft Screen, Focus Spotlight and Invisible Notes need no permission. Flashbang Protection and Keystroke Display need Input Monitoring. Color Picker and Screenshots need Screen Recording.
Which hotkeys can I change?
Only the Studio tool hotkeys can be changed in the app, each on its own card: Laser Pointer, Drawing, Flashlight and Keystroke Display. The hotkeys for Color Picker, Screenshots, Focus Spotlight and Display Presets are fixed.
Do the tools work on more than one display?
Yes, each in its own way. Laser Pointer, Flashlight and Keystroke Display show on the display that holds the cursor, and Flashlight dims the other displays plainly. Drawing starts on the cursor's display, and Clear removes ink on every display. Focus Spotlight keeps one region at a time, on the display that holds your frontmost window. Soft Screen and Color Grading cover every display. Color Picker and Screenshots use the display under the cursor. Display Presets hotkeys act on the display under the cursor, and its editor saves for the built-in display only. Display Schedule can target all, internal or external displays.
Which macOS versions are supported?
macOS 13 or later. Screenshots is not available on macOS 14.0 to 14.3.
I bought Pro before October 18, 2026. Do I get Studio?
Yes. Studio is free if you bought Pro before October 18, 2026.
