What it comes to building a schedule this APP makes life so much easier. It eliminates errors in counting days and puts durations at my fingertips. A total favorite.

The Date Wheel works as advertised and is quite simple to use. Good to have as an APP on the iPad for when one is in a meeting and needs to correctly calculate a date forward or backward.

I’ve used this app for years. It’s awesome! Perfect replacement for a physical date wheel!

I use this app to calculate deadlines in my law practice. It’s very useful. I’ve used others that are not nearly as functional as this one. Highly recommended.

Super tool for work and other uses.
The best.

Nice Clean App. app sticks to the basic calcs and has a large display that is uncluttered and simple enough so a concentration-challenged person like me can use it during meetings.
I rated 4 instead of 5 for two reasons
1. In the wheels the year is easy to change by mistake which I don’t find easy to notice. (This can have significant effects and go un-noticed when calculating out a certain number of weeks.)
2. It would be convenient if day of week were included in the date wheels (happily it is in the results). I know this sounds like more clutter but not having it there causes me extra steps.

The app it self is a huge help at work. When explaining to my clients their time window it is a life saver. My only issue with the app is that it cannot be viewed landscape. If you have an app for iPad, especially if I have to pay for it I should have the option of how it is viewed.

When I quickly need to provide a date based on xxx days/weeks/months from some other date, this is my tool of choice. Couldn't live without it.
Johnny Appleseed Fan • Jan 5, 2018
It needs to be updated for iOS 11 and iPhone X, but it works great and is a good date wheel calculator!
125shifter • Dec 27, 2017
While some people have pages and pages of app; one for everything, I have only a few... I’m not not crazy about using my smart phone over living a real life... however, this app is used all the time in my world; strategic project management and execution. While I am a “tactile guy”, my date wheel is always in my pocket with this app. Easily worth the investment in exchange for the value received.

The company name “creative algorithms” is appropriate. It lets you use months, weeks, days for its measurement. But it appears to only use days to calculate.
When I use dates to go for exactly 10 years measured by months, from the first day of one month to the 31st of the 120th month, the calculation shows me at 121.3 months.
I don’t know if they’re still updating this app but it’s basically useless unless you’re calculating days apparently.
RESPONSE: Creative Algorithms responded to me. They state that they indicate their interpretation of “months” is financial months. I’ll leave that to you to evaluate. It wasn’t that clear to me as of 11/2017.

I use this app daily for work. My job requires me to calculate specific time points based on a starting date (3, 6, 28 mos out). I like that I can save each time point separately. What I would like to see is a way to use the same start date without having to put it into each of my saved time points. I would also like to see +\- (+ 2wks or - 2 wks from start date) if that's possible.
All in all I'm quite happy with this app.

This is a nice app. Very helpful when I'm working out my development schedules. A project manager's must have app.

Good app for tracking dates and durations. You can save your calculations on certain items for future use and review which I like and find helpful.

Frequently used. Staff are curious how I can predict dates so fast. Best and most useful purchased app.
The Real Danno • Jul 28, 2016
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 don't include the beginning date, but do include the end date. (e.g. 3 days from July 3 is July 6, right? Not if you don't have the end date set correctly in this program.) This program automatically includes the beginning date and let's 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.

Indispensable, I use it all the time.

This is a great app!

Keep track of days, business days, weeks, months until an event or since a significant event. It's a flawless little gem.
Update: still lovin' it after 5 years.
