To the standard and academic basic editions, Logos Bible Software has now added free access to “Cloud Basic.” Cloud Basic can be accessed via app.logos.com and run entirely inside a web browser.
At this point, it looks like markup still doesn’t yet sync into the web app or into the desktop or mobile apps from the web. So, if you decide to give Logos Cloud a try, you will want to note this limitation so that you don’t end up wondering where your notes went.
