imo.im

Keeping calls and messages together is the practical appeal of imo.im, a communications service for people who want voice and video calls as well as chat. Its familiar mix of messaging and calling makes it a straightforward alternative to using separate apps for each task. The main trade-off is that a messaging service is most useful when the people someone wants to reach are also on it; otherwise, another app may be needed. By our assessment, imo.im has a clear everyday purpose, though its value depends on the contacts and features a person needs. It belongs to the same broad category as other internet calling and chat apps.
