# 邮证 vs DVR

The clearest difference is rating: DVR at 2.6 against 邮证's 1.6. 邮证's advantage is review sentiment (13% vs 4%) and iOS requirement (10.0 vs 12.0). On price, ratings volume, update cadence and ads there is nothing between them.

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

DVR holds the better App Store score, 2.6 against 1.6. Both are backed by a comparable volume of ratings — 7 and 5 respectively. Written reviews complicate that: 13% of 邮证's written reviews are positive against 4% of DVR's, so the app with the better star average is not the one people write more warmly about.

邮证 ships an update every 2 months, DVR every 3 months. The most recent releases landed on October 12, 2026 and October 20, 2026 respectively.
