Write a thought in your own words, keep an optional next step, and return when you choose. A private shelf beside the familiar tactile stones. HOW IT WORKS 1. Tap Thought shelf from the stone screen, then Write a thought. Add an optional next step in your own words. 2. Keep the entry Open, set it aside for Later with an optional revisit date, or File it. Return to add a follow-up; edits preserve the original entry and creation date. 3. Search your writing, reopen filed entries, share a saved entry explicitly, or permanently delete it after confirmation. Tactile stones, breathing, rituals, settling curves, reflections, stone gifts, widgets and settings remain available. A readable Stones/Tools header replaces the crowded icon row, and the interface now supports native iPad layouts. WHAT TO KNOW This is personal writing, not mental-health assessment or treatment. No emotion score or outcome is inferred. Revisit dates do not schedule notifications. Thought Shelf entries are separate from the existing stone-backup export; shared copies and operating-system backups are independent. iPhone and iPad.
