ReadFocus+:Reading Ruler, Mask

ReadFocus+ is a reading ruler, reading overlay and focus aid for Android. Use a translucent line highlight or reading mask on top of any app — ebook readers, browsers, PDF, news, comics — to stay on the right line, reduce eye strain and read with deeper concentration.

─── HOW IT WORKS ───

Grant the overlay permission once. A semi-transparent focus strip floats on top of any app. Drag it to the line you are reading and your eyes stay on track instead of wandering or skipping rows.

─── TWO FOCUS MODES ───

• Line Highlight (Reading Ruler) — Illuminates your current line so your eyes never wander

• Reading Mask (Page Mask) — Dims everything except your reading zone for tunnel-vision focus

─── FULLY ADJUSTABLE ───

• Focus strip height (50dp–300dp) — match any font size

• Opacity (10%–100%) — from a soft tint to a deep solid color

• Corner roundness — sharp bar or smooth pill
