# UUID vs 聚媒优视(B)

The clearest difference is update cadence: 聚媒优视(B) at every 9 days against UUID's every 2 months. UUID's advantage is iOS requirement (13.0 vs 15). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

UUID ships an update every 2 months, 聚媒优视(B) every 9 days. The most recent releases landed on September 23, 2026 and September 25, 2026 respectively.
