App is great as it has info from 1492 to late 1800s. Would like to see the 20th and 21st century add ons like Apollo and the events and people who made history . Know 20 th century had USA involved in major wars from WW1 to desert storm and then into the conflicts of the 21st century like September 11 and Afghanistan and IRaq. Otherwise app is very informative and worth the price. Looking forward to these additions in next update. Thanks
