ReceptionRating · Positive reviews · Number of ratings

4Voice Communicator holds the better App Store score, 4.8 against 2.7. That said, the two scores are not equally well evidenced: 4Voice Communicator has 243 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 0% of 4Voice Communicator's written reviews are positive against 22% of NUSO's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

4Voice Communicator ships an update every 4 months, NUSO every 2 months. The most recent releases landed on October 18, 2026 and October 13, 2026 respectively.
