03 / THE STUDIO
Good tools come
from paying attention.
To the calculation that needs checking. The task that could be simpler. The small detail that makes a tool feel right.
Aphelion is an independent software studio led by Bijan Adinehpoor, an electrical and renewable-energy engineer. We bring that practical perspective to everything we make.
