Towsemi's PWM Fix Blue Light Filter is an Android app that helps keep your eyes healthy while using your smartphone. It blocks blue light and glare, reducing the power consumption of your device and preventing OLED screen burn-in.

The app has a smart three-stage blue light filter that maintains 99% of the color and clarity of your original screen. It also features a night filter with super dark mode that surpasses the limits of hardware.

With Towsemi, you can easily control your brightness with gesture control by sliding right or left. The app also has a built-in screen shot feature that allows you to take screenshots without the effect of the filter. Additionally, Towsemi supports TV remote control and auto-run on boot/restart.

One of the most notable features of this app is the PWM Flicker-Free Fix, which gets your phone 0 PWM flicker and fixes the green screen on low brightness. Towsemi also offers experimental voice control, which allows you to call out the app's name three times loudly to fade any glare that enters your eyes through the screen.

Overall, Towsemi's PWM Fix Blue Light Filter is a free and easy-to-use app that offers numerous benefits to keep your eyes healthy, protect your phone, and prolong battery life.
