The new app pulls together journalism from both titles in a single digital edition, published once a week on Thursdays.
The Times of London Weekly is designed to be a digestible read that provides a snapshot of news and opinion writing in Britain, covering affairs both at home and abroad.
The app will be available in 46 countries and can be purchased through the Apple iTunes app store, with Google Play stores to follow. It is available on both smartphone and tablet.
Readers will get a one-month free trial, after which the app is priced at the equivalent of £2.99 a month in local currencies.
