# 倒数日历 vs HiDays

The clearest difference is in-app purchases: 倒数日历 at none against HiDays's 1. 倒数日历 also leads on iOS requirement (11.0 vs 17.0). HiDays's advantage is update cadence (every 8 days vs every 5 weeks). On price, ads and device support there is nothing between them.

Both are free to download. HiDays sells 1 one-off in-app purchase. 倒数日历 asks for nothing beyond the download.

倒数日历 ships an update every 5 weeks, HiDays every 8 days. The most recent releases landed on October 24, 2026 and October 4, 2026 respectively.
