DateTime - Date and Time Calculator App Reviews

this is the smartest app I have seen for a long time and it becomes very handz in a lot of situations. This will soon be a number one app everybody wants and has on his or hers iPhone

Tried a few calculations. I now can finally add time. Very hard with a regular calculator. I look forward to an iPad version soon.

I use this to calculate when my breaks will end when I miss them. I cant believe how easy this is to use. It perfectly suits my needs

After I dowmload the app and pay for it, it tells me that the multiply and divide buttons cant be used with dates and times. I know that I swam for 30 minutes at a rate of one minute and seven seconds per 50 meters. Simple division should tell me how far I swam. Im not sure what the point of this app is if it cant divide dates and times.

App does not count the current month when counting months. For example, April 2011 to June 2012 is 15 months counting April but the app is giving me 14 - it does not count the initial months and that is what I paid for it to do.

This app used to be the best, but it had not been updated in years and with the more recent versions of iOS, it crashes all of the time. Save your money unless you see an update after 2016.

What a great app!

This is an excellent date and time calculator. OTOH - Its only a so-so numeric calculator, as it does not follow standard arithmetic rules. 1+2*3 should always produce 7 (seven), yet it produces the incorrect result of 9 (nine).

Does what it advertises. Calculates dates great. Its missing business days though.

Does what it says

I really like this date time calculator, but it would be nice to have a backspace key to correct entries and not have to start over.

The usefulness of this app is surprising. Didnt know how many times I actually wanted to have this type of information for scheduling. Definitely needs a backspace feature as well as business days, but its pretty useful as is.

The way it handles date/time math is really simple and fast. I wont throw my scientific calc away yet tough.

I would make note of start time and then track a duration of behaviors using a stop watch. Thanks to this app I can pinpoint the exact time each durational segment began, without having to lose transition time. With this app I am also going to be able to organize a curriculum. and... :)

I wanted a scroll thing to pick and old date

As a part time yacht delivery captain I can estimate my distance and speed but would like to enter a date and time when I would like to arrive and subtract my estimated travel time to obtain a desired date and time to depart. Of course I can do this with paper and pencil but this would be so much easier with this app if it is possible. It probably can but I cant figure it out.

very well done. Only suggestion are: add a backspace key and do an rpn version, please.

App is OK and does what it says. What it doesnt say and what you cant do is divide and multiply times. So if you run 5 10K races this year, you can add up all your times to find the total, but you cannot divide by 5 to get your average time. You cannot get your average speed on your bike ride. How hard can that be?

This is a fantastic app and I can foresee many uses for it. For example, I have to get up at 5:30AM; how many hours of sleep will I now get? Would be even greater if it had calculations for business days, which I use a lot. For example, this contract expires in 160 business days; what date is that? That would be so wonderful in a future update.

Its literally a date calculator, and I really mean a date calculator. What a genius idea and implementation. Much kudos to the developer. 5/5
