# International Calling－Talk360 vs Spectra Protocol

The clearest difference is in-app purchases: Spectra Protocol at none against International Calling－Talk360's 11. Spectra Protocol also leads on ads (none vs shown) and rating (5.0 vs 4.7). International Calling－Talk360's advantage is ratings volume (21K vs 1) and review sentiment (66% vs 50%). On price, device support and iOS requirement there is nothing between them.

Both are free to download. International Calling－Talk360 sells 11 one-off in-app purchases. Spectra Protocol asks for nothing beyond the download.

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.

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