# Anniversary vs 时间倒计时

The clearest difference is in-app purchases: 时间倒计时 at none against Anniversary's 3. 时间倒计时 also leads on device support (3 vs 1) and iOS requirement (15.6 vs 17.0). Anniversary's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 5 weeks). On price there is nothing between them.

Both are free to download. Anniversary sells 3 in-app purchases, starting at $0.99 per month. 时间倒计时 asks for nothing beyond the download.

Anniversary ships an update every 3 weeks, 时间倒计时 every 5 weeks. The most recent releases landed on October 15, 2026 and October 16, 2026 respectively.
