Pros and cons of Date Wheel date calculator app for iPhone and iPad

Date Wheel date calculator app good for

I love this app! Its a great tool. Only feature I would add is an alarm you could set to warn you that your deadline is approaching or has reached a certain point.
Simple just the way it should be for checking delivery or start dates
Keep track of days, business days, weeks, months until an event or since a significant event. Its a flawless little gem. Update: still lovin it after 5 years.
If you depend on an app that clearly shows accurate due dates, be careful with this app by ensuring you have the "include end date" properly set in settings. Many people dont include the beginning date, but do include the end date. (e.g. 3 days from July 3 is July 6, right? Not if you dont have the end date set correctly in this program.) This program automatically includes the beginning date and lets you set whether to include the end date. Turning end date on in the above example gives you July 5. The program should be a little clearer with the effect of this option.
Frequently used. Staff are curious how I can predict dates so fast. Best and most useful purchased app.
The ability to save calculations is very nice for keeping track of project deadlines and completion dates and to see at a glance how many weeks and days are left before the deadline. If it had time duration in "years" I would definitely give it 5 stars.

Some bad moments

... is it not possible to save actions!! I can see the saved ones but cant call them back. Also I miss e.mail support for sending data to my account and it would be nice to see in the line of the saved the days for comparison. Also I miss a clock, remembering deadlines end. The price for such a simple thing is toooooo high. Thanks.
I asked them to include iOS calendar integration so I dont have to exit the app, go into the standard calendar app and re-enter the information. Instead of a practical upgrade I got lipstick on a pig.
Very disappointed. Expected to use this on my iPad but does not work in landscape mode.
I primarily bought the app to calculate the dates for my garden harvest. Once I had the app, I tried a sample calculation for my retirement date... When the results were off I tried the web version. I input my November 2007 start date, 360 months, the results were both June of 2037. Just ball parking the disparity, Im guessing the month value is hard coded at 30 days. REALLY?
I add to August 7,2014 6 Months, the result which I got is Feb 3 ,2015. While the correct calculations is Feb 7, 2015.by using other two Apps, could you clarify this.
I loved this tool until I found a major problem with the way the tool calculates months: 11/14/16 - 11/24/20 1472 days 4.032877 years 48.39452 months Plug these dates into the calculator and 49.06667 months are calculated!!! (This is because the tool is using 30 days/month calculation INSTEAD of the true 30.41667 days/mo over 12 months). I would give this tool 5 stars if there was not this algorithm issue. In my nature of work I need exact durations so sadly I cannot use it.
