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
