Date Calculator PW for Android

I used this app everyday at work and it was great. As of the last IOS update, it no longer works. Please fix it.

This app no longer works with iOS 11.2.5.

Was a very nice app to use, after the update on 1/23/18 App screen blank and no longer works, please fix

This app is a great help in determining the next date 70 days from the last date I picked up a commemorative coin or perhaps the time between two special events, I think however this app lacks 2 things: first, it doesn't correctly figure the number of days between dates if one or both are in a Leap Year such as 2000, 2008, or 2016 for example. second, why have just days when you can also have years, months, weeks, hours, minutes, and even seconds or at least a menu letting me choose between 1 and all 7 from years to seconds! Please consider adding one or both suggestions in case you happen to update this app🤗. :)Thanks very much:)

First, this app comes with no instructions or documentation. It basically does let you get the difference between two dates and add or subtract an amount to a given date, all good. When entering a date, if you omit the year, it seems to default to 2000; the current year would be a nicer default. Fortunately there is a button for Today. There is a button to set the unit-- day, week, month etc. It works fine on my Android, but on my Mobile Air, it always sets to Months and the selection box immediately disappears. Bad! There is no built-in Help. The author Web page links in the App Store must be a joke-- they go to some unrelated blog.
