Time to Time is a simple yet powerful time calculator for working with times and durations. It's perfect for freelancers, on-site technicians, businesses or anyone who wants to make working with times easier!

Use it to find the duration between two times, add hours and minutes to a time, subtract hours and minutes from a time or perform complex calculations with any combination of times and durations.


• Calculate the duration in days, hours and minutes from one time 'to' another time.
• Add and subtract with hours, minutes and times of day.
• Perform complex calculations using multiple times and durations in the same expression.
• 12 and 24 hour time modes including a mixed mode for using both time formats in the same expression.
• Smart 12 hour calculations allow the app to automatically detect whether times entered are 'am' or 'pm' e.g. 9 to 5 = 9am to 5pm.
• Times can be added in a wide variety of styles such as 9, 9am, 915, 0915, 9:00, 3pm, 15:00, 1500.
• A 'now' button for quickly entering the current time.
• Access help and settings right from within the app.


Calculate how many hours you worked today:
9 to 5 - 10 to 10:15 - 1h =

Find out how much sleep you'll get from now until 7:30am:
'now' to 7:30am =

Add up all of today's jobs:
9 to 10:13 + 10:45 to 11:30 + 2:30pm to 4:37pm =

Add an assortment of time durations together:
1:13h + 2h + 0:15h + 28h + 17:45h =

Great, but i can’t divide my time


I love everything about this app, except that i can’t divide the time.. this app was everything i was looking for and needed i love it except that the developer forgot to include a division button.. why?? I need to divide my time too.. please add it on an update. Thanks.



This is a great application to use at work. I use it ever day so to work but I wish it could calculate not just hours by minutes too.

Time to Time calculator- EXCELLECT!


I read about this app on the iPhone life daily app email and got it right after reading about it.
Several weeks later and I feel that the app is so simple but works PERFECTLY. And yes, time can be calculated just like any other numerical series, but just as with the myriad of available number calculators this app makes time calculation just as easy.
Although I got it for my iPad 3 and it is an iPhone app, the 2X scaler still looks good on the iPad and my ipod Touch 3rd gen.
OK, at $1.99, it IS a bit pricy for an app, I think 99 cents would be better. But that said, I also have no trouble paying and supporting the developer of a good app, and this app is to me! If you have a situation or continuing need for this time calculator, I highly recommend it!
