Your feelings, rendered as light.

A check-in starts with one honest moment. Choose from forty-nine feelings, add a line if it helps, and keep moving. Streaks can mark continuity without turning a missed day into a verdict.

Over time, Mental grows with you. Its upcoming memory layer will remember what matters, revise its understanding as your life changes, and occasionally surface something useful. Most moments do not need a conclusion.

The growing picture still belongs to you. Your journal stays on your iPhone and in your private iCloud. Memories can be corrected or forgotten, optional features remain your choice, and the main data paths are explained.
