Related, the alternation between the Old and New Testaments is something I’ve been considering to keep readers engaged. (And something which Bible Reading Plan Generator allows automatically.)
However, this is the first plan I’ve seen that has a referral program (see others' videos below).
Having not seen the actual plan, I cannot comment on specifics. However, with my core characteristics in mind, my sense is that it is a significant daily investment and may not follow the church calendar.
