this app's books are okay, and it has a free point system, but it has this infuriating "unlock next chapter" feature that automatically takes my points and applies them to the chapter AFTER the new one i haven't been able to unlock. why would i ever want this??? really very annoying if i'm honest edit: dropping a star because the books increase in price as you go on and it's incredibly annoying to read them. it also self- promotes through annoying popups
