I run a book club where the club members read 60 books a year (https://www.sixtybooksayear.com/). When reading at a pace of ~5 books/month, there are skills you develop to increase your storage of concepts from any given book, but also your ability to synthesize ideas across books.

I've compiled some of my best working knowledge into this app on how to become a serious reader. Bram's Reading App will help you: (1) set questions you want answered before you even pick up a book [Questions Over Completion], (2) answer those questions as you read with deliberate annotations [Commonbase], and (3) learn to read and manage multiple books at the same time [Discursive Reading].

Other Features include: Widgets and Control Center Shortcuts, Save from Share Sheet, Configurable Per Book Reading Notifications, Vector Embedded Annotations Across Books, Reading Sessions with Live Timers, A Tactile Progress Wheel, Nested Commentary, Full Text Search, Quiz Mode (next release), Micro Essay Builder (future release)

I hope you enjoy, and let me know if you have any great tips about being well read!
