RustDesk Remote Desktop holds the better App Store score, 4.2 against 3.7. That said, the two scores are not equally well evidenced: RustDesk Remote Desktop has 78 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 67% of AbtoVoIPClient's written reviews are positive against 59% of RustDesk Remote Desktop's, so the app with the better star average is not the one people write more warmly about.
AbtoVoIPClient ships an update every 5 months, RustDesk Remote Desktop every 2 months. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
