Posting with permission...   This is not Logos related, but it is quarterly related, for those who have been wanting the quarterlies on either iPad or Android here is a potential solution for you.  E-sword is now available for both iPad/iPhone as well as Android systems I do not  have a lot of experience with iPad and have only just discovered the android version myself so am unable to answer questions, but I will with the other information post a link to a help site dedicated to e-sword that will be able to help.  Here is the link where you can download the apps for each https://www.e-sword.net/ipad/links.htm and here is info about converting them for idevices https://www.e-sword.net/ipad/faq.htm#:~:text=How%20do%20I%20transfer%20my%20user%20files%20to%20a%20new%20device%3F and for android https://www.e-sword.net/android/faq.htm (helpful site for questions about converting, etc http://www.biblesupport.com/topic/11739-news-e-sword-updated-the-module-converter/) and here is a link that has the quarterlies already formated for desktop e-sword so you would only have to convert and import https://steenberg.us/sharpeningthesword/sts-a-2017-xxx_002.htm

  1. Dawn, for the SS quarterly on mobile, you can't beat the Sabbath School app. I use it on iOS, both phone and tablet, but I'm sure there is an Android version also. It has the verbatim quarterly texts with live links to the Bible texts in several versions, ability to highlight text and record your notes, includes the EGW supplemental notes, and even includes audio, read by a real person not AI voice. I highly recommend as a stand-alone mobile solution for the SS Quarterly. As far as I know, there is no desktop equivalent. The downside is that there is no integration with other apps such as Bible readers. That is what I like about Logos; When reading a text, I can see an icon for a note I made in a previous study, open it and review the note. In Sabbath School app, you would have to be in the particular lesson to see your note. Also I don't know how long your notes last. In Logos I am still seeing Notes I put in decades ago.
