Good for reading, not writing. I've been trying to edit my books for MONTHS and it refuses to work. Can you just stop spoiling the premium users and fix your damned app without breaking it more? You also get one ad after each chapter which is extremely annoying. Can you start to listen to the people who use your app that don't want to pay for a useless subscription? I don't care about the ads but it's the editing books, people want me to continue my book but I can't do that anymore.
