Shijima Diary
Read full descriptionHide full description
A diary app for gently setting down your thoughts and finishing your day in silence. "Shijima Diary" (Diary of Silence) is a quiet space designed to help you "set down and let go" of your thoughts and feelings. Write a little about your day before going to bed. An AI will receive your words briefly and occasionally ask a gentle question. After a few exchanges, the conversation naturally draws to a close. This app is not designed to sustain long conversations, nor is it intended to solve problems. It is simply designed to let you vent a little, feel heard, gently lighten your heart, and quietly transition into tomorrow. Note: The AI features in this app require a device that supports Apple Intelligence. Compatible devices include iPhone 15 Pro and later, iPhone 16 series and later, and iPad models with M1 or A17 Pro chips or later. Even on supported devices, you must enable Apple Intelligence in Settings > Apple Intelligence & Siri. On non-compatible devices, the AI features—such as receiving your input and asking questions—will not function, which means the app's core features will be unavailable. ■ Features AI that listens briefly and asks gentle questions.
