A private journal for the nights you can't share with anyone. Some feelings are too tangled to say out loud. Some words would shatter if spoken. NightWhisper is a quiet, dark lake — only the moon listens here. ■ Tonight's moon, tonight's feeling Every entry is paired with tonight's moon phase. New, crescent, full, waning. Reflect on your tides through the moon's cycle. ■ Ten emotion tags Secret, longing, loneliness, conflict, wish, anger, tenderness, fear, forgiveness, nostalgia. Name what you couldn't name. ■ Night Letters Choose from 18 gentle prompts across Unwind Today, Let Your Heart Rest, and Leave It for Tomorrow. Pick a prompt and continue directly into tonight's journal entry. The first card in each theme is free to try. ■ A Moonlit Word (Premium) A short moonlit word returns to what you write. No advice. No judgment. Just witness. On supported devices, an on-device model responds. On other devices, the app selects from its curated moonlit words. ■ Calendar & Search Look back at past nights through a moon-phase calendar. Search by feeling, by keyword.
