McCann London won a Silver Lion for its "friend compass" work with the travel comparison website company Momondo Group.
R/GA London was also a winner with a Bronze Lion for its work for Beats Music, while JWT London picked up Bronze Lion for "Android Kit-Kat", its work for Nestle.
Leading the way for awards in the mobile category was Brazil, with 12 wins, including the Grand Prix, three Silver Lions, three Gold Lions and five Bronze Lions.
The Grand Prix went to "the protection ad" for Nivea Sun Kids, which was created by FCB Brasil and involved a wrist strap for kids that linked to a mobile ad in case children ran off while on the beach.
In second place was the US with two Golds, two Silvers and six Bronze Lions.
Last year, UK agencies received three Lions, including a Gold Lion for SapientNitro’s "get cash" for Royal Bank of Scotland.
