How can I fairly use copyrighted bible translations in an app?

[This question](https://christianity.stackexchange.com/questions/16377/what-major-translations-of-the-bible-are-in-the-public-domain) establishes that most copyrighted translations have a fair use clause allowing for up to 500 verses to be used. [This question](https://christianity.stackexchange.com/questions/25814/can-i-project-more-than-500-verses-of-scripture-over-the-course-of-a-year-or-a) further clarifies that the 500 word limit is "reset" each week in the case of a pastor projecting verses onto a screen in a sermon. Well, what about a program or app that makes available daily readings (always conforming to the fair use clause in a given day) but which, over the course of the year will show more than 500 verses total. Is it reset each day? This feels like a use of the translation *in good faith*, but I don't know how a lawyer representing a profit-seeking company would see it. Depending on how the program is written, that could further by complicated if the program: 1. stores the entire translation in a database, or 2. allows users to access "daily readings" from days other than today What do you think?
