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.

Simple as I need it

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 Real Danno ,

Be careful

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.
