For iOS
The full Java Jenny Mod does not exist for iOS. iPhones only run Minecraft Bedrock, which cannot load .jar files, Forge or Fabric. What iOS players can install is Jenny-themed Bedrock content: skins, addons, textures and worlds delivered through the Jenny Mods and Addons app on the App Store.
What iOS players can actually install
Skins with Jenny-themed outfits, casual variants and HD or 3D character options. NPC packs with basic companion animations and simple AI movement. Roleplay worlds with custom houses and themed maps. Texture packs with soft colour palettes or HD art. Mini-games, challenge maps and matching sound packs.
How the iOS app works
Download the app, browse the catalogue, tap Install on a pack, and the app opens Minecraft Bedrock and imports the files automatically. Behind the scenes the app is still delivering Bedrock addons, not Java code.
The app uses a weekly auto-renewing subscription after a free trial, managed through the standard Apple ID subscription settings.
What is not possible on iOS
Loading the Java Jenny Mod .jar directly. Running Forge or Fabric on iPhone. Using the exact same NPC, dialogue and item behaviours as the Java build. Anything advertised as a "Jenny Mod APK" or "Jenny Mod for iPhone Java" is not the real Java mod.
