I use both an iPhone and an iPad. There are two widgets which I love, which do the same thing. My kindle widget displays and opens me up immediately into the book I'm currently reading. My Goodreader widget (essentially a PDF reading/markup program I use a lot for research) allows me to pick a pdf to open up to immediately, to the place I was last reading in it. Goodreader, unlike Kindle, has multiple tabs, multiple things ope at once, so it's like Logos in that regard.
I would LOVE to see a Logos widget for iOS/iPadOS . Ideally, one you could configure a little, but I'd settle for a basic one that would open up to your preferred Bible, last spot reading. It would be a one-touch back into your daily Bible reading. Perhaps one could configure it to a particular book (not preferred Bible), or daily reading schedule (whether Bible or some other book.)
I use these other two widgets daily, and the ease really facilitates my reading. Would love to see it in Logos.
