It is a graphing calculator you own outright. One purchase covers iPhone, iPad and Mac. It works fully offline, with no accounts, adverts, trackers, subscriptions or locked functions.

Every result carries ≈ and an estimated uncertainty, because a numerical answer should say what it is rather than imply an exactness it does not have.
