Are you using multiple Bibles side-by-side? Or just a single Bible? When viewing selected verses in the side-by-side view, then use the buttons above each section of verses to change the font size. When viewing the Chapter window, or if using a single Bible only, then you can use the pinch/zoom gesture to make the font size larger or smaller. Demo screencast...
This is for the daily Bible reading. Also, I only use the nwt13 because it will not allow me to download the nwt study edition from jw.org Thank you
Hi Yvonne. Yes the Study Bible is not available in EPUB format which is required for the Bible app. The Weekly Bible Reading shows inside the Chapter window, so use the pinch/zoom gesture as described in step 2 above and as demonstrated in the demo screencast.
