Yahoo has released a new app called Livetext that lets users text videos to their contacts. The app is currently available in Hong Kong and Taiwan and will be available Thursday in the US, Canada, UK, France and Germany. The app is available on phones running Google’s Android or Apple’s iOS operating systems.

Over the past few years, Yahoo has worked to remake itself for the mobile era. CEO Marissa Mayer, who took over in 2012, has been focused on mobile, social, video, and native ads. The new Livetext app is the company’s latest attempt to amp up its mobile offerings. However, it may be a problem that the videos sent through the app to another person will arrive without sound.

Arjun Sethi, a Yahoo senior director of product management, gave a live demonstration of the app at a media event in Manhattan. Showing how to do quick video calls with friends, he could text back and forth with them but not talk directly to them. The company released Livetext earlier this month exclusively at Apple’s App Store in Hong Kong.

As more consumers have migrated to smartphones and tablets from PCs and small projectors, Yahoo have moved to improve its mobile offerings. Reviving its messaging services for smartphone users and refreshing the company’s other mobile properties is a matter of survival for the company. The company has seen its advertising sales slow considerably over the past few years and needs to find a way to increase revenue.

Yahoo has an impressive record with its mobile apps. The company won Apple design awards back-to-back in 2013 and 2014 for its Weather and News Digest apps. However, the company has had trouble gaining traction with its mobile apps. According to comScore, eight of the top 10 mobile apps in May were owned by either Facebook or Google, while Yahoo’s apps failed to make the top 15.
