About

DreamDejaVu!?

Features
Read full description

DreamDejaVu? is a private dream-journaling app. Users record or type their dreams, and the app uses Apple's on-device AI (Apple Intelligence / Foundation Models) to help them reflect — generating summaries, extracting symbols, offering interpretations, and surfacing recurring themes. All data stays on the device. There is no account, no login, no in-app purchase, no advertising, no third-party analytics, and no network calls except a one-time download of the on-device speech-recognition model on first launch. Important: the app requires iOS 26.4 or later AND a device with Apple Intelligence enabled. On an incompatible device, or with Apple Intelligence disabled, the AI features will not work. Please test on an Apple-Intelligence-capable iPhone (iPhone 15 Pro / Pro Max or iPhone 16 / 17 family) running iOS 26.4 or later, with Apple Intelligence turned on in Settings.
