# KeepCalling International vs SatSleeve

The clearest difference is in-app purchases: SatSleeve at none against KeepCalling International's 10. SatSleeve also leads on ads (none vs shown) and review sentiment (59% vs 39%). KeepCalling International's advantage is rating (4.6 vs 4.3) and ratings volume (19K vs 4). On price and device support there is nothing between them.

Both are free to download. KeepCalling International sells 9 one-off in-app purchases. SatSleeve asks for nothing beyond the download.

KeepCalling International holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: KeepCalling International has 19K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 39% of KeepCalling International's written reviews are positive against 59% of SatSleeve's, so the app with the better star average is not the one people write more warmly about.

KeepCalling International ships an update every 3 weeks, SatSleeve every 3 months. The most recent releases landed on November 3, 2026 and October 23, 2026 respectively.
