No account. No tracking. Your entries stay on your device. ◆ Write 3 good things a day - Three simple fields — small things count, even one is fine - Mood tags and photo attachments - Gentle writing prompts that change every day ◆ A warm word from AI - Once a day, AI reads your three things and replies with warmth - Not a summary or a score — a companion who savors your words with you - Weekly and monthly AI reviews to look back on your patterns ◆ Watch your record grow - Streaks, mood charts, and a calendar of your entries - A word cloud of the things you write about most - "A year ago today" and "This day last month" cards ◆ Your data stays yours - Everything is stored on your device - Optional automatic backup to your own iCloud - No ads, no tracking SDKs - Export as text, Markdown, JSON, or shareable images ◆ Also in Japanese - The app follows your device language (English / Japanese) - AI replies in your language too Start planting three small seeds a day, and grow a record that is truly yours.
