Helicon

Speed reading for your PDFs on iPad.

Speed reading in Helicon lights the words in front of your eyes and moves at your pace. Your eyes follow the light, and stop going back over lines you already read.

Free, for iPhone and iPad with iOS 26 or later.

Pick how the guide moves.

Light the line, a group of words, or both. Or show the words large in the middle of the screen, so your eyes stay still.

Start on any line, at your pace.

Tap a line to start there, and tap the lit line to pause. Set the words a minute, and change it in steps of 5, 10 or 25. Scanned pages work too: Helicon reads their text first.
