I totally love it! I appreciate that I can use it both on Android and PC (easier to copy some parts of text to keep as notes for myself in different Notebooks in OneNote to classify by subject; never tried Highlight or Remember options yet). It offers a wide choice of books but I'd love more of scientific or history books. Love the different growth plans, repetition cards, quizzes, collections & specially the Gems which summarize several books on a given topic. Would like, when I do a search, to have a sign in the result list that shows if I already have put the book in my library (or even finished reading it) & maybe possibility to have different categories/shelves in the library; also to do a search in my library (instead of in the whole of the app). Good to be able to sort library on Titles (instead of just date selected) & to mark summaries as Finished. Don't understand what the Download option does as the application doesn't seem to work when offline (when I did a search, it didn't show the one book I had downloaded, said "No summary found"; showed only Finished ones; maybe I must get more familiar with the app). I had one Short were it didn't pick up my choice (between self-confidence, self-awareness & self-discipline), it always showed self-awareness. I also don't know how to navigate the shorts. The section showing latest summaries is a bit short, can I sort books by date added to check only those added since I last had a look? I don't know how to change the "Categories you're interested in" (I have selected the max 3 goals). But, as I've said, I need more time to explore. I think the summaries are well-written & the app encourages you to discover more & improve yourself.
