BARCELONA,Spain,Feb. 25,2019 -- CooTek (NYSE: CTK),a previous winner for the Mobile Innovation Award at the GSMA Global Mobile Awards,today hosted a live meditation campaign through its popular mindfulness and meditation app "Breeze" at the Mobile World Congress 2019 ("MWC19") to showcase how it can deliver relevant entertainment and meditation content.

Campaign participants were able to take a 10-minute break from their busy lives to listen to relaxing music and follow a guided meditation through the Breeze app. A sofa and noise-canceling headphones were provided to each participant in order to mimic an ideal meditation environment. "Phones can not only be our connection to the world,but also our shelter from stressful life," commented Mr. Zhengchao Lu,Product Director at CooTek.

Along with Breeze,CooTek also showcased its global portfolio of apps which span across five select verticals including fitness,lifestyle,healthcare,news and short videos,and entertainment at MWC19. These apps include the feminine care app,"Cherry," which provides professional healthcare content and a community for users to discuss and share content related to menstrual cycles,relationships,fashion,and more. The Company also showcased its "VeeU" short video app which generates personalized content containing the hottest and funniest short videos.
