Facebook Messenger gets VOIP; Evernote adds document search

The update comes after Facebook already rolled out the feature in the United States and Canada in January. Facebook Messenger users will now be able to call each other directly through the service instead of passing voice messages to each other.

The Messenger VOIP feature in the United States was soon followed up with Facebook bringing the feature to its flagship Facebook app, and this may soon be the case in the UK and Europe.

Facebook Messenger for iPhone is available as a free download on Apple's iTunes App Store.

Evernote adds document search for premium, announces Deutsche Telekom deal

Popular productivity app Evernote made two announcements on Monday regarding its premium offerings. The first was the addition of a new document search feature for Evernote's premium users. Premium subscribers will now have the option to search through note-attached files created in MS Office, iWork, and OpenOffice.

The company also announced a new partnership with carrier Deutsche Telekom, which will see Deutsche Telekom customers in Germany provided with free access to Evernote's premium features for one year. The offer, worth about €40, is available to all Deutsche Telekom subscribers including fixed line, broadband, and mobile for the next 18 months.

Germany is Evernote's second largest market in the Europe, Middle East, and Africa region. Of Evernote's 50 million worldwide users, 1.33 million are located in Germany. Twenty-nine percent of the company's users are located in the United States, with another 20 percent based in Japan.

The strategic partnership with Deutsche Telekom is aimed at getting users to try out Evernote's premium features in the hope that they will continue their subscriptions after the free trial is over. The Wall Street Journal reports that premium subscription fees — typically running about $45 a year or $5 per month — account for about 98 percent of Evernote's revenue.
