# 扫描仪 vs 证件照

The clearest difference is update cadence: 证件照 at weekly against 扫描仪's every 3 weeks. 扫描仪's advantage is iOS requirement (10.0 vs 12.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 扫描仪 sells 4 in-app purchases, starting at $4.49 per 7 days and 证件照 sells 2 in-app purchases, starting at $6.99 per 3 months. Whichever you choose, the download price is not the number that matters.

扫描仪 ships an update every 3 weeks, 证件照 weekly. The most recent releases landed on September 19, 2026 and May 17, 2026 respectively.
