Heliograph

A native space-weather watch for iPhone, Apple TV, Apple Watch, and Vision Pro. Current conditions and short-horizon forecasts from NOAA and NASA, each stamped with its real "as of" time. Aurora for both poles; plain-language grid, GPS, and HF impact.

At the farthest point of the orbit, motion slows.

Aphelion exists for the people who actually do the work. Engineers checking a calculation against the standard. Electricians sizing a cable on a job that has to pass inspection. Consultants signing a report whose numbers will be tested against reality. Our software is the layer between the brief and the answer that holds up.

We build for precision without friction — calculations that pass review, references that load on a poor connection, interfaces that respect the time of someone with a meter in one hand and a phone in the other. Nothing here is generative; nothing here is approximate. Either it is right against AS/NZS and IEC, or it is not shipped.

We are an independent studio. We are not venture-funded. We answer to the work.
