Caff flashes your text one word at a time, pinned to a single focal point. Your eyes stop darting across the page — so you read articles, docs, and email in a fraction of the time, and spend what's left actually thinking.
Ordinary reading spends most of its time on tiny eye jumps — finding the next word, refocusing, occasionally backtracking. Caff removes the jumps. The words come to one place; you just look.
Caff lines every word up on the one letter your brain uses to recognise it, and marks it. The focal point never moves — only the words do.
Start gentle while you warm up, then push the dial. Caff also paces itself — lingering on long words and punctuation so meaning has somewhere to land.

Every word is aligned on its optimal recognition point — one letter, marked, always in the same spot. Your gaze stops hunting.
No slide, no fade. Words simply replace each other. For eyes and brains that find movement noisy.
Pick the typeface that reads easiest for you, size it up, and Caff remembers it everywhere.
Lost the thread? One tap stops the stream; swipe back to replay the last sentence at the same pace. No scrubbing through a wall of text.
Caff lingers a beat on long words, commas, and full stops, then picks the pace back up — the rhythm you read with anyway, automated.
White word on true black. Easy at 1am.
A faint pulse keeps the rhythm without sound.

No connection needed once the text is in.
