Readrrr: one word, one red letter.
Each word appears in the same spot with one letter marked in red. Its full version needs a subscription or a $99.99 one-time purchase.
Readrrr shows a word. Flincth shows the thought.
Readrrr flashes your books one word at a time, sells its full version by the week, month or year, and needs iOS 18. Flincth Speed Reader also groups words into phrases and short sentences, runs on iOS 17, and unlocks Pro with one purchase that your family shares.
Flincth: a word, a phrase or a sentence.
Read one word at a time, or let Flincth group words into phrases and short sentences at punctuation, so the text still makes sense at speed. Pause, and the whole paragraph is there.
Illustrative diagrams, not app screenshots.
Fewer frames, more sense.
Both apps keep your eyes in one spot. Flincth lets the words of a phrase arrive together, and costs less to own.

Why readers move to Flincth.
One word at a time is a good start. Reading in meaningful phrases, on the iPhone you already have, for one small price, is a better habit.
Phrases that keep their meaning
Word, phrase and sentence modes split text at punctuation, add natural pauses and give long words a little more time, so you go faster without losing the thread.
Pay once, or not at all
The free download has every reading mode and format. Pro is a single purchase with Family Sharing, and its 7-day trial asks for no payment and never turns into a charge.
What you read stays yours
No account and no AI. Documents are processed on your iPhone or iPad and never sent to Flincth; with Pro sync on, they travel only to your own iCloud.
Never lose your place
Pause to see the whole paragraph and tap any sentence to carry on from there. Each document opens where you stopped, a few words back.
Want to scan paper books with the camera or send articles from Safari? Readrrr does that. Flincth is built for reading your own documents in phrases that make sense, paid for once.
Good questions.
Is Flincth Speed Reader a Readrrr alternative?+
Yes. Both show DRM-free books in a fixed spot at the speed you set. Flincth can also group words into phrases or short sentences, runs on iOS 17, and Pro is a one-time purchase with Family Sharing.
Does Flincth mark a focus letter like Readrrr?+
Yes. In word mode a focus letter is highlighted, with optional guide marks above and below. With Pro you can pick its color or turn it off.
Can Flincth Speed Reader open Kindle or Apple Books purchases?+
No. Those books are protected with DRM, which the app cannot open. It reads DRM-free EPUB, PDF with a text layer, DOCX, TXT, RTF and Markdown, plus pasted text. Scanned PDFs without a text layer are not supported.
What do I get without paying?+
Every reading mode and every format, light and dark themes, a dyslexia-friendly font and all accessibility settings. The free plan has a daily reading time, a few saved documents and a speed cap; Pro removes them with one purchase.
Does the trial turn into a subscription?+
No. There is no subscription at all. The 7-day Pro trial is started by you, asks for no payment details and simply ends; Pro is a separate one-time purchase.
