First of all, thank you for creating a Medium account to read this story, Abbie. Means a lot to me and the work I put into these kind of stories 😇
Coming to the book tracking app of choice, I feel StoryGraph does justice to all bookworm needs - reading stats and graphs, better book review system. Not sure about what you exactly mean by gamification - as in notifications to remind you to read or unlocking achievements and setting reading goals? I feel both Bookly and StoryGraph would be able to do that but Bookly has a more prominent in-app purchase for its feature than SG.
For me, Book Tracker app's biggest appeal was because of it's Apple-like design. It's being actively developed so it gets updates frequently and feedback submission is also pretty amiable.
I would suggest starting off with StoryGraph since its free and then trying out Bookly to see if it has anything better to offer. And no worries, do let me know if you have more questions. Always, happy to help out someone trying to get back into reading 📖
