Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
UMC Client holds the better App Store score, 2.3 against 2.0. That said, the two scores are not equally well evidenced: GoGVTC has 45 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 0% of UMC Client's written reviews are positive against 33% of GoGVTC's, so the app with the better star average is not the one people write more warmly about.
UMC Client ships an update every 3 months, GoGVTC every 2 months. The most recent releases landed on October 20, 2026 and October 17, 2026 respectively.
