I used DoctrinalMastery a couple of years ago to memorize The Living Christ. It was a fantastic app, very easy to use, and it helped me achieve my goal. I don’t know what happened…there must have been an update but DoctrinalMastery was not improved. In fact, it is much worse, has many bugs, and is more difficult to use. I can’t add scriptures from gospel library unless it is a link from something else like a footnote that opens in the sidebar; and even then, it just copies and pastes it. It doesn’t do the memorization feature where you can take away the words like with the passages already on there. DoctrinalMastery is pretty good if you only care about the scripture masteries but as a graduated seminary student, I am looking for other content and the “my content” section needs some work. Also, side note, the scripture mastery lists on there are outdated, and they have since updated a lot of the scriptures, so it may be helpful to change that as well. Overall, this used to be a great app, and I think it can be once again, but your developers need to get to work. I will happily use it when that happens!
