# 拍照识物 vs 成语大全

The clearest difference is ads: 拍照识物 at none against 成语大全's shown. 拍照识物 also leads on iOS requirement (13.0 vs 18.1). 成语大全's advantage is update cadence (every 2 months vs every 45 months). On price, in-app purchases and device support there is nothing between them.

Both are free to download. 拍照识物 sells 7 in-app purchases, starting at $1.99 per month and 成语大全 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

拍照识物 ships an update every 45 months, 成语大全 every 2 months. The most recent releases landed on October 25, 2026 and October 14, 2026 respectively.
