A little quiet.
One more
word.
Open your book. Find your rhythm. Punctum brings each word to one point, at a pace that feels like yours.
How it works
Each word is aligned at its optimal recognition point, so your eyes stay on one spot instead of jumping from word to word. This is called RSVP — rapid serial visual presentation. You set the pace. The default is 300 words per minute, which is a speed research finds comfortable, not the highest number the screen can show.
Sometimes a book turns down the noise of the day. A window opens and the words come in. Take a small moment to read at your own pace. The story is waiting right here.

Adaptive speed
It learns where you slow down
Punctum watches where you rewind, pause and re-read, and builds a difficulty map of the book from your own behaviour. Dense passages get more time; easy ones do not waste yours. Nothing about this leaves your device.
Context strip
One line of context, when you want it
RSVP hides the sentence you are in. A single faded line of the words around the current one gives it back without moving the focus point by a pixel. It is off by default, because it also costs attention.
Warm-up and breaks
It starts slow and tells you to stop
The first words of a session run below your target speed and ramp up. After a long stretch, Punctum suggests a break — because single-word reading measurably raises visual fatigue, and blinking less is part of why.
Typography
Fonts that were made to be read
OpenDyslexic and Atkinson Hyperlegible ship with the app, with adjustable letter spacing. No download, no network. Both were designed for readers who find ordinary type hard to hold on to.

Questions
Will I still understand what I read?
Up to roughly 350 words per minute, research says comprehension is about the same as normal reading. Past that it starts to drop, and inference goes first. Punctum defaults to 300 and tells you when you cross into the range where the evidence stops supporting you.
What files can I open?
TXT, PDF and EPUB. Scanned PDFs — pages that are images of text rather than text — are not supported yet; Punctum tells you instead of failing silently.
Do I need an account or an internet connection?
Neither. There is no sign-up, and the app works with no network at all.
Where do my books go?
Nowhere. They are read from your device and stay there. There is no upload, no sync, and no server that could hold them.
What does it cost?
There is a free tier with a lifetime reading budget, generous enough for several books. After that you can buy a one-time pack of books or an unlimited yearly plan. No ads, and no subscription required to keep reading what you already read.
Which languages does the interface support?
Eighteen, including right-to-left layout for Arabic and Urdu. Book language is detected separately, and sets your starting speed.
