Ratings and Reviews
Interesting, Informative, Fascinating
Few people appreciate human history because they are completely unaware of the events that have shaped our world. This app gives you a fascinating, daily glimpse into compelling historical events. Events which are as important now as they were back then. Society cannot improve if you don't understand the past.
Nice App, but...
The icon for the app does not reflect the current date-Reflects & stays at the date that the app was purchased. Although when app is opened up the correct day does pop up which I find a bit annoying & tacky, especially since it is not that hard to fix this inconsistency.
Daily Must-Read, but ...
Great way to start each day. The links to Wikipedia articles for each item are an excellent feature.
One star deducted for occasional factual errors (see below), and use of obscure units of measure, such as Mw fot earthquake intensity.
Error example: 20 January 1953 says Eisenhower was the first US Presidenr inaugurated on 20 January in accordance with the 20th Amendment. Not true. The 20th Amendment was ratified in 1933, and Franklin Delano Roosevelt was inaugurated for his second term on 20 January 1937.
