What's New in Flash Reader

4.0.1

November 5, 2026

The first update since the comeback, shaped by what you told us in week one. • Paused on iPhone? Scroll the text with your finger and tap any word to read on from there. • Contents in the ⋯ menu jumps to any chapter. • On iPad and iPhone Duo, the text beside the word keeps your place in view. • The + and Search buttons, and the X on every sheet, answer the first tap, every time. • Big books import faster and Notion pages come through more reliably. • Library swipes are easier to read in light and dark, the app icon is a touch sharper, and many languages read more naturally.

Ahead of its time and very simple to use.

Who would have thought years later that this type of concept would be integrated into short form videos on platforms like TikTok, YouTube, and Instagram for the captions. This app is the only ways re cents that I have completed reading books. I just wish it had fancy text like the captions on the newer videos.

Rubbish

Doesn’t allow to open modern websites

Major flaws

It was good until it restarted the book I was reading, which is a pretty big issue since you can’t skip around. These two things make it pretty much unusable.

Don't get tricked

Free app that works with Pocket? Nice!
Nope, gotta pay to sync with pocket
Alright, it's an investment
Nope, since I log onto Pocket using my Google account, I cannot connect it to Flash.
Ugh
Back to research

*FOLLOW UP*
I clicked help and I got asked to enable notifications.... Magically, the "skip" button is not working but the "ok" worked alright 🤦🏻‍♂️👎🏼
