SkyFlux

The night sky,
on your horizon

Aurora radar that knows the Kp your latitude actually needs, a meteor-shower calendar, eclipses, and a 3D solar system you can fly through — with no ads, no account, and nothing tracking you.

Your horizon, not a percentage

Most aurora apps show the chance overhead — 0% while the sky glows green to the north. SkyFlux tells you the Kp your own latitude needs for the aurora to reach your horizon.

Meteor showers & eclipses

Every major shower with its radiant live on the sky map, and eclipse timings for where you stand — computed on the device, months ahead, offline.

Point it at the sky

An AR sky view corrected with the World Magnetic Model, so the compass points where the stars actually are. Red night mode keeps your eyes dark-adapted.

Quiet by design

No ads. No account. No analytics. Location leaves the phone only rounded to a ~60 km² cell, for the cloud forecast and a place name — nothing else, to no one else.

Privacy is the feature. SkyFlux ships with zero third-party SDKs and keeps every computation on the device. What little the app fetches from the network, and why, is written out plainly in the privacy policy — it fits on one page.
