ReceptionRating · Positive reviews · Number of ratings

Ooma Office holds the better App Store score, 4.9 against 2.5. That said, the two scores are not equally well evidenced: Ooma Office has 9.5K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 100% of gTalk PBX's written reviews are positive against 50% of Ooma Office's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

gTalk PBX ships an update every 3 weeks, Ooma Office every 6 weeks. The most recent releases landed on September 24, 2026 and October 27, 2026 respectively.
