ReceptionRating · Positive reviews · Number of ratings

Spectra Protocol holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: International Calling-Talk360 has 21K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 66% of International Calling-Talk360's written reviews are positive against 50% of Spectra Protocol's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

International Calling-Talk360 ships an update fortnightly, Spectra Protocol weekly. The most recent releases landed on October 18, 2026 and October 14, 2026 respectively.
