# 中国联通 vs TimeStamp Camera+MAP

The clearest difference is rating: TimeStamp Camera+MAP at 4.3 against 中国联通's 2.5. 中国联通's advantage is in-app purchases (none vs 4) and ratings volume (1.3K vs 6). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. TimeStamp Camera+MAP sells 4 in-app purchases, starting at $7.00 per 7 days. 中国联通 asks for nothing beyond the download.

TimeStamp Camera+MAP holds the better App Store score, 4.3 against 2.5. That said, the two scores are not equally well evidenced: 中国联通 has 1.3K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 37% of 中国联通's written reviews are positive against 24% of TimeStamp Camera+MAP's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 weeks. Both last shipped on October 16, 2026.
