Hour Difference Calculator

V3.0 is a complete rewrite from the previous version. There are many new features and optimizations for iOS 8 and iPhone 6, 6 Plus, and iPad

If you need an accurate calculator to instantly find the hours and minutes between two times, then this is it. It is designed from the ground up to help people who constantly work with times, and it works in either “hours + minutes” or “hours.decimal minutes”. Not only does it work in both formats, but it will instantly convert from one to the other depending on what the user prefers. Finding the time between two times is as easy as entering the start time and end time with the time picker and the answer is displayed in both formats.

There are three tools to help people manage times more efficiently. The “Time Difference” tab works with known times and calculates the time between them. The “Add / Subtract” tab works with a known block of time and a start or end time; then it will calculate the required start or end time to equal the block time. The “Time” tab allows quick addition or subtraction of times in either format.

A new feature for V3.0 is the addition of the “History” tab. This allows blocks of time to be saved to a list that can be emailed in text format or comma separated format to allow easy import into spreadsheets. Times can also be saved to the devices calendar.

This app does have advertising, but it can be removed using the “Remove ads” in-app purchase located on the more page.
