Love this app but one request

Cat Yon

I've been using this app for months now and love it. One improvement I would like to see is on the time calculator tab in addition to the the total hours to also see the hours converted to minutes. For example if the time difference is 4:00 to also show 240 minutes.

Couldn't be without it!


I work for a small business that uses time sheets instead of computers to log employee time. This app completely takes the guesswork and estimations out of calculating my working time. I also love the calculator!

Great update

listens for a living

This app does all the calculations I need to do with time. Very few app do that. This new update made it much better. I can now add all my times much faster then before.
