# 企业微信 vs 1CalendarS

The clearest difference is review sentiment: 1CalendarS at 100% against 企业微信's 17%. 1CalendarS also leads on rating (5.0 vs 2.5). 企业微信's advantage is in-app purchases (none vs 2) and ratings volume (25 vs 3). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. 1CalendarS sells 2 in-app purchases, starting at $1.99 per month. 企业微信 asks for nothing beyond the download.

1CalendarS holds the better App Store score, 5.0 against 2.5. That said, the two scores are not equally well evidenced: 企业微信 has 25 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 17% of 企业微信's written reviews are positive against 100% of 1CalendarS's.

企业微信 ships an update monthly, 1CalendarS every 3 weeks. Both last shipped on October 24, 2026.
