This application allows you to calculate time (hours and minutes). You can calculate things like 1:30+0:50. When you enter a number, ":" is automatically inserted to separate the hour and minute, so you can calculate quickly. This is useful for calculating total work hours, time spent on daily errands, and travel time. You can add, subtract, multiply, and divide. The calculation history is automatically saved, so you can check it later. A memory key is provided, allowing you to save and add subtotals. Minutes that are often used for calculations (15 minutes, 30 minutes, etc.) can be registered and used for one-touch addition. A button to add 24 hours is provided for calculations when crossing days. It comes in a variety of colors such as orange, green, cyan, pink, and black, and you can choose the one you like best. [ List of functions ] You can calculate hours and minutes, or minutes and seconds. You can check the calculation history, and touch the answer displayed in the history to reuse it for calculations. The memory keys can be used to save, add, and subtract subtotals. By setting the preset keys, you can use the most frequently used time (minutes) for calculation with a single touch. The color of the application can be selected.
