Let your sky
come to you.
Most apps wait for you to open them. Celestium watches the sky on your behalf, and reaches out on the days that actually meet your chart.
Personal Moments
Celestium watches for the rare days a transit meets your chart. It tells you when one is here, when one is forming, or when the sky is simply quiet. Mark the ones that land; they gather into a small constellation that stays yours. No counts, no streaks; just the moments worth keeping.
Sky Letters
On a moment that matters, seal a note to a later self. It comes back to you when the sky turns, at the next New or Full Moon or a date you pick. Sealed and unopened until then.
Moment's Sky
Moment's Sky reads the chart of this moment on its own terms: the sky as it actually stands overhead, before you read it against yours.
