Hey. I’ve been using MemoWrite for quite a while and it’s probably the easiest option I’ve found for this. You get 50 questions about your life, but all of them are available from the start, so you can answer whenever you have time. You can write or record your answers and add photos, then they turn everything into a printed book. I also found a Reddit review comparing memowrite with Storyworth, which is worth reading if you’re considering both.
