# SeeLock vs 倍速時計

The clearest difference is ads: 倍速時計 at none against SeeLock's shown. SeeLock's advantage is update cadence (every 6 days vs every 3 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. SeeLock sells 6 in-app purchases, starting at $1.99 per month and 倍速時計 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

SeeLock ships an update every 6 days, 倍速時計 every 3 weeks. The most recent releases landed on October 28, 2026 and October 25, 2026 respectively.
