Shabtab is built for using your phone at night: it softens the screen, reduces blue light, and helps ease eye strain and sleep trouble after looking at the display in the dark.

Why Shabtab ?

• Dims the screen below Android’s minimum brightness (with a safe upper limit)

• Blue light filter with adjustable warmth

• Automatic schedule: turn on and off at times you choose

• Sunrise/sunset schedule for Iranian cities (works offline)

• Home screen widget for quick on/off

• Quick Settings tile in the notification shade

• Notification controls while the filter is on (dimmer / brighter / off)

• Optional system brightness lowered when the filter starts, restored when it stops

• Emergency off: shake the phone at very high dim levels

• Light and dark theme, font size, Farsi and English

• Lightweight, fast, and no intrusive ads

Good for:

Night reading, messaging, late-night browsing, and anyone bothered by bright white screens in the dark. On AMOLED displays it can also help save battery.

No account is required for core use.
