Date Finder for iPhone and iPad

A new iPhone/iPad app, Date Finder, has been launched. It is said to provide valuable assistance to people researching their family history. It helps overcome a common problem in genealogy research such as differentiating between documents which refer to people of the same name, but are different individuals. Date Finder allows you to cross-reference a person’s age at a date from one document to their age at a date on another document to see if they align.
So when you have two historic documents and you want to establish whether they relate to the same person - Key in date and the persons age on one document into Date Finder. You can then cross reference ages and dates from other documents to see if they are consistent and refer to the same person.
It is available from the App Store: http://itunes.apple.com/us/app/date-finder/id511832753?ls=1&mt=8 for 99 cents
