# Calendar Reminder vs 防伪QR码

The clearest difference is in-app purchases: 防伪QR码 at none against Calendar Reminder's 1. 防伪QR码 also leads on ads (none vs shown) and iOS requirement (15.0 vs 17.6). Calendar Reminder's advantage is update cadence (fortnightly vs every 11 months). On price and device support there is nothing between them.

Both are free to download. Calendar Reminder sells 1 one-off in-app purchase. 防伪QR码 asks for nothing beyond the download.

Calendar Reminder ships an update fortnightly, 防伪QR码 every 11 months. The most recent releases landed on October 31, 2026 and October 27, 2026 respectively.
