CtrlBright was created by ApakaTech to give Windows users a simple, lightweight way to control their screen brightness — without hardware limitations getting in the way.
Many Windows monitors don't expose hardware brightness controls through software, leaving users stuck at a fixed brightness level. Late-night work, dark environments, and eye strain become real problems without a proper solution.
We built CtrlBright to solve that. A lightweight virtual overlay that dims your screen exactly as much as you need — without drivers, without complexity, and without ever appearing in your recordings or screen shares.
Simple, powerful, and always in control. That's the CtrlBright promise.
"We wanted a tool that simply gets out of your way. CtrlBright should feel invisible — except for the perfect brightness it gives you."
Every feature decision starts with one question: does this make the user's experience better and simpler?
CtrlBright collects no data and works fully offline. Your screen, your settings, your privacy.
We obsess over keeping CtrlBright tiny and efficient. It should never slow you down or drain your resources.
We listen to user feedback and ship updates that genuinely improve the experience — not just version bumps.

We're a dedicated team of developers and designers focused on building software that solves real, everyday problems for Windows users. CtrlBright is our flagship utility — and it reflects our commitment to doing one thing exceptionally well.
The ApakaTech team identified a gap: Windows users with monitors that lack hardware brightness control had no good, lightweight solution. CtrlBright was conceived.
Months of R&D went into the capture-safe overlay technology — ensuring the control window stays truly invisible in screen recordings, shares, and screenshots.
First public release of CtrlBright for Windows 10 and 11. Features overlay controls, prismatic effects, automatic startup, customizable shortcuts, and full capture-safe privacy.
