This app is wonderful. It has helped me tremendously. I use it to memorize entire chapters but I find it frustrating having to maintain my health bar on chapters that I know. I understand that when you're first learning a chapter that it's necessary to review it on a regular basis but it'd be nice if after many weeks of maintaining a full health bar the frequency of type outs could be less. When you've got a dozen or so chapters memorized but feel the need to maintain your health bar on each one, it makes it harder to move on to new scriptures. Maybe there could be different levels of mastery so that when you've mastered a particular passage, the number of type outs required to refill the health bar would diminish. It seems like now it's about twice a week to refill the health bar. So, if I've maintained a full health bar for 6 months, it doesn't seem necessary to continue doing 2 type outs a week to keep it full. I don't know exactly how often it should be. Maybe once every two weeks for mastered passages.
