Reviewers mostly see Async as a practical way to handle work voice messages with less back-and-forth. They repeatedly praise transcripts, easier catch-up for people who cannot listen right away, and a clear place to track updates and reply across multiple topics. Several say it saves time, works well with colleagues and external contacts, and feels more personal than email. A few also note that voice will not replace written communication or meetings in every case. The main sharp criticism is privacy: one reviewer says the terms allow overly broad data use.
