Give any screen the soft look of e-ink

EinkReader is a free e-book reader for Android. Its main feature is contrast control that recreates the calm, paper-like picture of an e-ink display on an ordinary phone or tablet, plus quick control of backlight and warm light to spare your eyes. No ads, no tracking.

Day theme: soft grey text on a white page, like e-ink — Day: soft e-ink look

Night theme: pure black background — Night: pure black

Two-page spread on a tablet in the day theme — Tablet spread

Comfort for your eyes

The value appears on screen while you swipe. Taps and horizontal swipes still turn pages.

Try it: drag the sliders

Backlight

Contrast

Warmth

In the app you swipe up or down on a third of the page and the value appears on screen.

Contrast like e-ink. A black-level setting lifts pure black to a soft dark grey and keeps the page white, so text is no longer a harsh black on glowing white. It is stored separately for day and night, so the night page can stay deep while the day page looks like paper.
Backlight strength. Brightness is set right inside the reader, down to 1%, so reading in the dark is gentle.
Warm light. A warm tint, adjustable from none to strong, takes the blue edge off the screen in the evening.
