Hi Bryan,
We currently don't have such a feature in either of our mobile apps (either iOS or Android) - however, I think we can definitely add this to our growing list of feature requests for those platforms.
Additionally, I should point out that Dozuki is pretty darn responsive. So, go ahead and navigate to a category on any Dozuki site (say, iFixit.com for example): https://www.ifixit.com/Device/MacBook_Pro_13%22_Retina_Display_Early_2015
There you'll be able to get your neatly, sectioned-off segments of guides on a mobile device!
