Outdated and no updates – HP 12C Financial Calculator Review

If you are using a reasonably modern iPhone, which has no “home” button anymore, then the only way to switch apps is to power down your iPhone. It insists on going into full screen mode and never relinquishes the screen. Outdated, outdated, outdated. This is an orphaned app.
