Different strengths
Neither app is strictly "more featured" — they lead in different places. LNReader brings external trackers (AniList, MyAnimeList, Kitsu, MangaUpdates), cloud backup, and incognito reading. Grimoire brings private GitHub repositories, EPUB sources (browse and fetch from Z-Library, Libgen and the like as if they were any other source), source login with locked-chapter support, NovelUpdates integration, ElevenLabs text-to-speech, and PIN-locked hidden categories.
