Optimized for the latest version of iOS, "Calculator HD" brings you a perfect blend of simplicity and ease of use like never before. In the vertical basic mode, you will never accidentally press those large, finger-friendly keys; while the horizontal scientific mode provides you with all the functions you need for your daily calculations—those functions you will actually use, not just decorative embellishments.
