About this app

Reading shouldn’t feel exhausting.

Seriatim Reader transforms books into a calm, focused flow designed for your phone. Forget overwhelming blocks of text, constant page turning, and losing your place. This is reading made for focus.

How it Works Import your book and tap "Start." The interface disappears, presenting your book one sentence at a time in a vertical feed.

* Tap to advance.
* Swipe to navigate.
* Focus entirely on the words.
* It reduces cognitive load, making dense books feel lighter and easier to finish.

Built for Focus & Neurodiversity We stripped away the distractions that make traditional reading apps difficult for many. Whether you have ADHD, get overwhelmed by "walls of text," or just want to read more on your commute, Seriatim helps you maintain momentum.

* Focused-style anchors guide your eyes to word beginnings.
* Letter-by-letter reveals smooth out the reading pace.
* Haptic feedback gives you a tactile sense of progress.

Read Your Way: Everything is customizable. Adjust text size, spacing, and reveal speed to match your brain’s processing style. If you get stuck, built-in local AI tools let you translate text, listen via text-to-speech, or ask questions about the plot to the local AI, all without leaving the page.

* Private by Design: Your library belongs to you.
* Import EPUB and PDF files easily.
* Works 100% offline.
* No accounts, no tracking, no ads.
* All processing happens on your device.

Rediscover the joy of finishing a book. Download Seriatim Reader and start reading differently.

5 Stars! Best and most unique reading app I use. It's an instant focus hack without requiring effort because the app sets the parameters for you and eliminates distractions you'd otherwise encounter with a typical reading setup. Adjust the settings until you find your pace and comfort. Reading on a phone as opposed to a tablet or a PC is much more enjoyable and keeps me reading longer. Highly recommend. My favorite app on the store.

This is great. I was looking for this type of pdf reader, which can optimise the view for the phone screen. previously I used the WPS office which has a phone screen mode. The animation speed cannot be changed from the settings screen, the slider won't work, I need to play the intro again to change the value. If you need more info, let me know.

one feature I wish this app had is the ability to search for text. sometimes I go back and forth between reading a book and listening and I search for the words of the sentence I just listened to, to find my place. if that gets added. 5 stars this app is pretty cool for reading ebook! update: dev is super responsive and super quick. My suggestion has been added already and extra as well.

Definitely in for a 5 star experience. Nathan, would you be willing to connect on Discord so I can better get an idea about the ideal experience? (I have a hunch, but I'd like to double check it with you) Update: It's now implemented - case sensitive and allowing for typos :)
