Predo
Predo by Cappsule Technologies

One word. One beat. A speed-reading app that flashes a book at you one word at a time, anchored to the eye's natural fixation point. Reading speed quietly doubles. The book stays the same.

Pick a text. Set a tempo. Predo serves the words exactly where you're already looking — at the optimal recognition point. No saccades, no backtracks, no skim. Education and Productivity, fully localised in EN + TR.

§ 01 — How it works

Three beats.

No saccades. No re-reads. Pick a text from the library, set a tempo, watch the words pass through the strike — the optimal recognition point your eye is already locked on.

01
Pick a text.
Choose from the curated Library — short essays, long-form non-fiction, classics — or paste in something of your own. Predo splits the text into RSVP-ready word units in a beat.
02
Set the tempo.
Start at 240 WPM. The dial steps in 20-WPM increments, all the way up to 800. Most readers settle around 400–550 within a week — without losing comprehension.
03
Read the strike.
Words flash at the fixation point, with the optimal recognition character lit in coral. Your eyes don't move. Your reading does. Pause, rewind, change tempo with one tap.
§ 02 — In the wild

Three screens.

The full loop: pick from the library, run the reader, look back on what you've read. Every session lands in your own iCloud — quietly synced across iPhone and iPad.

§ 05 — Built for

Small details, chosen on purpose.

Native SwiftUI for iPhone and iPad. Your library and stats live in your own private CloudKit — never visible to us. The reader does its work entirely on-device.

Strike at the ORP.
Each word is offset so the optical recognition point lands exactly on the coral strike. Your eye doesn't have to hunt — the rhythm does the work.
Tempo, in 20-WPM steps.
From 200 to 800. Long words automatically pause longer; punctuation breaks add a half-beat. Comprehension stays intact while the dial creeps up.
iCloud, privately.
Your library, history and tempo settings sync via your private CloudKit database — present on every device you sign into, never visible to us.
Bring your own text.
Paste a URL, drop in plain text, or import via the iOS Share Sheet. Predo cleans, splits and serves it through the reader in a single tap.
Stats, read like a chart.
Weekly WPM, words read, sessions, retention. A single-page weekly review that compares you against your last seven days — never against anyone else.
EN + TR, fully set.
Both languages are first-class. Library texts, tempo presets and timing rules adapt for Turkish — including how the optical recognition point falls on suffixed words.
§ 06 — Small print

The usual questions.

What you'd ask first. If we missed something, drop us a line.

Does RSVP actually make me read faster?
Yes — by skipping the eye saccades and re-fixations that normally pace your reading. Comprehension on familiar topics matches or exceeds traditional reading at 400–500 WPM for most people. Dense or unfamiliar text is harder; that's why we let you slow down on the fly.
Why a coral strike?
Each word has an Optimal Recognition Point — the character your eye uses to identify it, usually around the first third. Predo aligns every word so its ORP lands on the strike, and lights that character coral. You stop hunting for it.
Is the library localised?
Yes. Library texts, the interface and the timing rules are fully localised in English and Turkish. Turkish suffixes change where the ORP falls, so the alignment routine has a separate path for them.
What about imports?
Pro adds the import flow: paste a URL, plain text, or use the iOS Share Sheet to send anything from Safari, Mail or another app into Predo. Imports clean automatically and live alongside the library.
Where does my data live?
In your own private CloudKit database. Library state, custom imports, history and stats sync across your devices via iCloud — none of it is visible to us. See the Privacy Policy for the full breakdown.
Does Predo track me?
No analytics SDKs, no ad tracking, no cross-app identifiers. We only collect anonymous crash data so we can fix what crashes. Sign-in with Apple is mandatory but we ask for zero scopes — your name and email never reach us.
Is Pro really lifetime?
Yes — a single in-app purchase tied to your Apple ID, restorable on any device. No subscription, no auto-renewal, no surprise charges. New library texts and reader features land for everyone holding Pro.
How do I delete my data?
In-app: Settings → Account → Delete Account. Removes your iCloud-synced library state, wipes your history and revokes your anonymous identifier. Apple handles the Sign-in with Apple side automatically.

Ready, set, read.

Editorial speed-reading from a small studio in Istanbul. Free to try — three starter texts, no card. Pro when you want the full shelf.
