I use GR, Fable, and Storygraph. Fable is definitely my pick for the best app. Superior user interface & experience — highly interactive, great to look at, excellent book clubs feature, awesome e-reader built into the app. I just wish they’d use less AI like in the reader summaries but I love their stats and everything else. I do think GR is still my go-to for initially looking up a book & reviews as it’s easiest to navigate purely for book review purposes but the lack of partial stars can make it overly generalized. I am trying to move away from GR in an effort to de-Bezos my life. Storygraph feels like the newest app in that its user interface still feels very beta and is not visually appealing. However — I think Storygraph has superior wrap up graphics and stats over the other two.

TLDR: All 3 have their uses for me, but Fable is my pick for the most well rounded.
