Musical.ly has begun redirecting users of its Live.ly app, which it decided to kill off last month, to a competing app called LiveMe. Existing Live.ly users are being pointed to LiveMe through an in-app message, it says. While it’s a fairly common industry practice for companies to direct users to similar apps or services when a product of theirs is being sunsetted, in this case, Musical.ly’s decision to close down Live.ly and send users to LiveMe was actually a contractually obligated part of Musical.ly’s nearly $1 billion acquisition by Chinese technology company Bytedance last year.

A clause in Bytedance’s agreement to acquire Musical.ly stated that, if the deal went through, Musical.ly would have to close Live.ly within six months, according to a source with knowledge of the deal.
