I recently discovered an excellent feature in the Kindle app: a “reading ruler.” When enabled, the app displays a translucent coloured bar over the text at a certain position in the page. Screenshot:
You can change the colour, the height, and the style of the bar.
I find it speeds up my reading considerably, but I would never want to import most of my readings (PDFs) into the Kindle app. Is anyone aware of a PDF reader with such a feature? Ideally one that can open files in place (to avoid the import-export do-see-doh).
I’ve looked at Highlights, PDF Expert, PDF Viewer, and Flexcil, to no avail.
And yes, I realize I could probably use an actual physical reading ruler (gasp) to accomplish this, app-agnostic… I’m thinking about it!
There’s also an app called overlays that works pretty well, and it’s not PDF specific. I don’t know if there’s an iOS version as I’m not an iPhone user.
Of the main offerings I’m only aware that Kindle offers this; even Apple’s Books and the common library apps (Libby and Bluefire Reader) do not. Given that it’s potentially an accessibility tool I assume it’s technologically difficult to implement? No idea. I have it enabled on Kindle too, I don’t really need it but I find it helps me focus.
I would be loathe to move any PDFs to Kindle though so I’d rather go without than do that!
