Functionality – HP 12C Financial Calculator Review

The HP 12C works fine on my iPad, but on my iPhone is is merely a regular calculator. It doesn’t matter which way I turn the phone, it stays the same. Is there something I am missing? If it doesn’t work on my iPhone, I might as well carry my physical 12C with me as it is a lot smaller than my iPad! Scratch that, I went into setting and turned on “Landscape Lock” restarted the program and it is now working.
