Shabtab — Comfort for your eyes at night

Is your phone's screen still too bright at night, even at its lowest setting? Do your eyes feel tired after using your phone in the dark, or do you struggle to fall asleep? Shabtab is built for exactly this.

By placing a soft layer over your display, Shabtab lowers the screen brightness below Android's minimum level, and with its blue light filter (warm mode), it reduces the eye strain, headaches, and insomnia caused by looking at your screen at night.

Features:

• Precise, continuous screen dimming — even lower than your phone's minimum setting

• Adjustable blue light filter to make the display warmer and more pleasant

• Quick controls from the notification (dimmer / brighter / turn off)

• Optional automatic lowering of system brightness when the filter turns on, and restoring it when it turns off

• A safe limit that prevents the screen from going completely black

• Lightweight, fast, and free of intrusive ads

• Full support for Persian and English (RTL)

Shabtab is perfect for reading at night, browsing before bed, and working in low-light environments — and on all displays it also helps save battery.

Shabtab is made by the Bluesi team — a small, passionate group that believes in building simple, high-quality, user-focused tools. Your feedback and suggestions are the light that guides us to make this app better.
