# 中文輸入法 vs OtterBoard

The clearest difference is ads: 中文輸入法 at none against OtterBoard's shown. OtterBoard's advantage is update cadence (every 3 days vs fortnightly). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. 中文輸入法 sells 2 in-app purchases, starting at $0.99 per month and OtterBoard sells 8 in-app purchases, starting at $5.99 per year. Whichever you choose, the download price is not the number that matters.

中文輸入法 ships an update fortnightly, OtterBoard every 3 days. The most recent releases landed on November 1, 2026 and October 29, 2026 respectively.
