I would love to see a version of this app on Windows in some capacity, whether as an app or website. I find it easier for myself to be on my computer just simply due to the ease of access and I would imagine it would be easier to not only see but being able to see more at once during exercises like Reorder and Wordbank.
If this were implemented, I would also suggest the implementation of "cross-platform" accounts. I have purchased the ESV translation for my Android app and would hate to lose access to it if I were to use a new platform for the app.
(Love the app, keep up the good work!)
