# Watch ID vs SecondHand

The clearest difference is ads: Watch ID at none against SecondHand's shown. SecondHand's advantage is update cadence (every 10 days vs every 13 months) and iOS requirement (15.1 vs 17.2). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Watch ID sells 2 in-app purchases, starting at $1.99 per 7 days and SecondHand sells 3 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

Watch ID ships an update every 13 months, SecondHand every 10 days. The most recent releases landed on November 4, 2026 and November 5, 2026 respectively.
