Open toolPicking the right dark tool
Each tool covers a different part of the day. Here is how to choose one without digging through the menu.
Most people start with the PDF reader, because documents are where a bright white page hurts the most. A contract, a textbook or a scanned report can mean dozens of pages of glare. Open the file, pick a tone that suits the room, and keep the original on your own device while you read.
Writing and planning happen at a different pace. A dark notepad or a focus timer keeps the screen quiet while your attention is on the work itself. Use them together: draft in the notepad, then set a timer for one block of focused work before you come back to the text.
For long reading
Use a warm or green tone in the evening and a classic tone in daylight. Lowering the brightness of your screen often helps more than a darker page alone.
For night writing
Write in short blocks and look away from the screen between them. Changing focus every few minutes rests your eyes better than one long stretch in front of the same bright light.
For focused work
Work in 25-minute blocks with a short break after each. A fixed end time makes it easier to stop, and the break is the moment to stand up and look at something far away.
