Your history works offline and returns after sign-in.
A working copy remains available on your iPhone without a network connection. After sign-in, the history synchronizes with your account.
A journal for state and personal rhythm
In the morning, note your state and choose three areas you want to give attention to. In the evening, compare that intention with how the day unfolded. Lunar gathers the entries into a personal Orbit — without scores, mandatory streaks, or ready-made diagnoses.

Living Orbit
Record your available energy, mood, bodily sensations, and direction of attention.
This is neither a task list nor a limit. Simply choose three areas you want to give attention to today.
Compare the intention with how the day unfolded. Over time, the entries form your personal Orbit.
Real app screens
A day begins with a brief check-in. Over time, entries become a calendar, an Orbit, and careful observations grounded in your history.

The day starts with your state and three areas of attention, not a score.

One point connects available energy, direction of attention, and the feeling of the moment.

Individual days form a cycle history where gaps remain visible.

Recurring patterns are phrased carefully and always link back to specific entries.
Over time
Individual traces form an Orbit and reveal the movement of your personal rhythm. Gaps remain empty, and every observation can be connected to specific days.
Principles
A working copy remains available on your iPhone without a network connection. After sign-in, the history synchronizes with your account.
Cycle and lunar phases can provide context for observation, but they do not explain or predict your state.
Lunar does not score consistency. You can skip any day — an empty space is not treated as an error.
Lunar helps you observe changes in your state. It is not a medical service, does not diagnose conditions, and does not replace consultation with a healthcare professional.

Many trackers demand discipline, score consistency, and often offer interpretations that sound more certain than the data allows.
Brief observations and three chosen areas of attention can reveal change without adding more control.
A morning check-in, Day Budget, evening reflection, and personal tools come together in a history called the Orbit.
A missed day remains an empty space — not a user error and not a reset of the entire history.
