Best app so far

I’m not one to write reviews, but I think this app needs more attention. This is one of the best free AO3 readers to use. They also listen to complaints, because I reported a bug and then a few hours later, they fixed it. Truly fantastic.

Response from developer

Thank you so much—and thank you for reporting that bug! I’m glad I could get it fixed quickly. My goal with AO3X is simple: to make reading your favorite AO3 stories more comfortable and enjoyable. Reader feedback helps shape what I improve next, so hearing this means a lot. Happy reading! ❤️

The tag blocking is a game changer

Finally, I can block tags once and have them stay hidden everywhere instead of rebuilding filters for every search or fandom. It sounds like a small feature, but it makes
 browsing so much better. Honestly one of the main reasons I use this app.
