multiple operation calculator vs iCalcHandy

A calculator that calculates and displays four arithmetic operations and free time at the same time.

As iPhones get larger, the keys on calculator apps have also gotten larger. Many people find the keys too big and difficult to type. If you make the keys smaller, the overall size of the keys also gets smaller, so you can move the entire keys to the right or left. If you hold the iPhone in one hand and operate the keys with your thumb, it is easier to use if the entire keys are closer to the operating hand. In general, you hold the iPhone in one hand and operate it with the index finger of the other hand, but even in such cases, it is easier to use if the entire keys are closer to the operating hand. "I wish I could choose the key size" "I wish the entire keys were closer to the operating hand" iCalcHandy is a calculator app that fulfills this request. In addition, iCalcHandy has a unique display. "What value did I enter?" "Was the value I entered correct?" Everyone has such worries when using a calculator. iCalcHandy displays the input value as it was entered even after calculation, so there is no such worry.
