# LocalStamp vs 一键水印

The clearest difference is in-app purchases: 一键水印 at none against LocalStamp's 1. 一键水印 also leads on update cadence (every 6 days vs every 3 months) and iOS requirement (16 vs 18.5). LocalStamp's advantage is ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. LocalStamp sells 1 one-off in-app purchase. 一键水印 asks for nothing beyond the download.

LocalStamp ships an update every 3 months, 一键水印 every 6 days. The most recent releases landed on November 9, 2026 and November 5, 2026 respectively.
