Why LumiMax?

There are already XDR brightness boost apps out there. None of them were good enough.

The Problem

  • 💸Too expensive — Most XDR boost apps charge way too much for a simple brightness tool.
  • 🔅Not bright enough — None of them actually push to the full 1600 nits your display is capable of.
  • 🎨Colors get distorted — Gamma table methods shift your color accuracy, ruining the XDR display's true potential.
  • đŸĒĢBattery drain — Gamma-based boosting keeps the backlight maxed out at all times, killing your battery life.

The Solution

LumiMax is built using Apple's native EDR (Extended Dynamic Range) overlay — not gamma table hacks. This means:

  • âœĻFull 1600 nits — Reaches the true maximum brightness of your XDR display.
  • âœĻColor accuracy preserved — No gamma shifting. Your P3 wide color gamut stays intact.
  • âœĻBattery efficient — Only boosts the overlay, not the backlight. Use less power than gamma-based alternatives.
